[0031] Figure 2 It is a flow chart of a method for evaluating a regional economic development index based on industrial chain analysis in an embodiment of the present application.

[0032] See also Figure 2 In an embodiment of the present application, a method for evaluating a regional economic development index based on industrial chain analysis is applied to a server. The method includes: S201, obtaining historical industry chain data of the new energy industry chain in the target area under target environmental parameters; In step S201, historical industry chain data for the new energy industry chain in the target region under target environmental parameters is obtained to provide reliable historical data support for subsequent climate and environmental impact analysis and environmental pressure scenario construction. As a complex industrial system highly sensitive to the natural environment, the operating efficiency, economic benefits, and stability of the new energy industry chain are significantly affected by various external environmental factors.

[0033] Target environmental parameters refer to a set of environmental variables that can reflect the climate and ecological environment characteristics of the target area and have a significant impact on the operation of the new energy industry chain. They include but are not limited to: temperature, humidity, wind speed, wind direction, precipitation, solar radiation intensity, air quality index, PM2.5 / PM10 concentration, surface temperature, soil moisture, etc. The selection of target environmental parameters is customized based on the energy type, geographical area characteristics, and industry chain structure. For example, for the wind power industry chain, wind speed and wind direction are key environmental parameters; for the photovoltaic industry chain, more attention is paid to solar radiation intensity and atmospheric transmittance; and in the hydrogen energy storage and transportation link, temperature and humidity may have a direct impact on material performance and safety.

[0034] During the specific implementation process, the geographical scope of the target area and the coverage of the new energy industry chain will be determined first. The new energy industry chain can include nodes and links in the upstream raw material supply, midstream production and manufacturing, and downstream energy storage and sales corresponding to industries such as wind power, photovoltaic power generation, biomass energy, and hydrogen energy. On this basis, by accessing multi-source data platforms such as local statistical bureau databases, industry supervision platforms, enterprise ERP (Enterprise Resource Planning) systems, and industrial park data centers, historical operating data of the new energy industry chain in recent years (such as the past 5 to 10 years) will be obtained. Historical industry chain data includes but is not limited to: production capacity, output value, energy consumption, carbon emissions, operating status of key equipment, raw material sources and delivery cycles, product inventory and outbound frequency, upstream and downstream collaborative relationships, logistics routes and costs, etc. of each node enterprise.

[0035] At the same time, by connecting to data from the National Meteorological Administration, the Ministry of Ecology and Environment, remote sensing satellite systems, and local meteorological monitoring stations, we extracted target environmental parameter data for the target area within the corresponding historical time period. To ensure effective data matching, we used a timestamp alignment mechanism and spatial gridding methods to synchronously map environmental data with industrial chain data.

[0036] S202. Analyze the impact of climate and environment on historical industrial chain data to obtain a set of node-layer impact factors and a set of link-layer impact factors for the new energy industry chain; Step S202 may include the following steps: identifying the climate response characteristics of the node operation data under the target environmental parameters; extracting the first influencing factor from the climate response characteristics to generate a node layer influencing factor set; identifying the link stability characteristics of the link interaction data under the target environmental parameters; extracting the second influencing factor from the link stability characteristics to generate a link layer influencing factor set.

[0037] Specifically, a climate and environmental impact analysis was conducted on historical industry chain data to obtain a set of node-level and link-level influencing factors for the new energy industry chain. This analysis aims to reveal the mechanism by which target environmental parameters affect different structural levels of the new energy industry chain, thereby constructing environmental pressure scenarios with realistic constraints. Because the operational characteristics of the new energy industry chain are highly sensitive to climate factors, and its structure typically includes multiple functional nodes (such as production, energy storage, and distribution) and links connecting these nodes (such as logistics, information transmission, and energy circulation), it is necessary to identify the specific influencing factors of environmental changes at both the node and link levels.

[0038] Among them, identifying the climate response characteristics of node operation data under target environmental parameters specifically includes the following steps: establishing a corresponding relationship between node operation data and target environmental parameters to generate a node-environment mapping matrix; based on the node-environment mapping matrix, calculating the sensitivity index of node operation data to the target environmental parameters; and determining the climate response characteristics of the industrial chain nodes according to the sensitivity index.

[0039] In one embodiment, to effectively identify the climate response characteristics of each node in the new energy industry chain under target environmental parameters, it is first necessary to establish a correspondence between node operating data and target environmental parameters to generate a node-environment mapping matrix. The node-environment mapping matrix uses the time series of node operating data as the primary dimension and environmental parameters (such as temperature, humidity, wind speed, solar radiation intensity, etc.) as the characteristic dimension. The two are associated through timestamp alignment and spatial position matching to ensure that the operating status of each node under specific time and environmental conditions is accurately mapped.

[0040] After generating the node-environment mapping matrix, sensitivity analysis can be used to calculate the responsiveness of each node's operating indicator to various environmental parameters, generating a sensitivity index. The sensitivity index can be quantified using correlation coefficients, regression coefficients, information gain, or feature importance scores based on machine learning models, reflecting the impact of changes in environmental variables on the node's operating status. To improve analysis accuracy, it is preferable to use a sliding window mechanism for local modeling of time series data and to introduce normalization to mitigate interference caused by different dimensions.

[0041] Finally, based on the numerical distribution of the sensitivity index, the response discrimination threshold is set, the highly sensitive variables are screened, and the characteristic variables that can significantly reflect the fluctuations of the node's operating performance with climate change are extracted, thereby determining the climate response characteristics of the node.

[0042] After constructing the node-environment mapping matrix, calculating the sensitivity index based on this mapping matrix, and determining the climate response characteristics of the industry chain nodes, the system extracts the primary impact factor from each node's climate response characteristics to generate a set of node-level impact factors in order to further quantify and structure the specific impact paths and response variables of climate perturbations on the functional nodes of the new energy industry chain. This set of node-level impact factors serves as a key input for subsequent environmental stress modeling and system response simulation. It characterizes the node's response elasticity, fluctuation amplitude, and reaction speed to different dimensions of environmental perturbations and forms the basis for constructing environmental stress transmission models and identifying target sensitive units.

[0043] Specifically, after identifying the climate response characteristics of each node, the system further performs statistical analysis and variable importance evaluation on its characteristic variables, extracting the dominant response variables that have a significant impact on the node's operating status, including but not limited to key climate factors that affect the node's operating efficiency, output capacity, and stability. To ensure the scientific nature of factor screening, the system uses principal component analysis (PCA), information gain ranking, mutual information scoring, or tree-based feature importance assessment methods to reduce the dimension and screen all response characteristics, eliminating redundant variables and noise variables, and retaining only the core climate factors that best represent the node response pattern as the first influencing factors. The extracted first influencing factors retain the corresponding response direction, response intensity, and fluctuation characteristics, and are structured and organized according to the node dimension to form a node-level influencing factor set. This influencing factor set not only describes the direct impact of environmental disturbances on individual nodes, but also has a unified data format that is quantifiable, comparable, and can be used for modeling, providing a data foundation for subsequent systemic pressure modeling and simulation.

[0044] After the node layer processing is completed, the system further conducts climate and environmental impact analysis on the data interaction relationship between the connected nodes in the new energy industry chain to identify the stability characteristics of the link layer structure under the disturbance of the target environmental parameters. As the functional circulation channel between nodes in the industrial chain, the stability of the link layer is directly related to the overall collaborative efficiency and continuity of the system. To identify the stability characteristics of the link layer, the system first collects historical link interaction data, including but not limited to logistics path timeliness, energy flow transmission on-off rate, link load change rate, communication delay and other indicators, and aligns them with the target environmental parameters in time to construct a link-environment mapping relationship, and then analyzes the state change law of each link under the influence of different climate variables.

[0045] Based on the aforementioned link-environment mapping, the system uses techniques such as volatility analysis, anomaly detection, and steady-state transition models to identify link stability characteristics. Specifically, these include the change in the link's stability range before and after a disturbance, the number of sudden changes, the distribution of recovery times, and the probability of link interruption. This process aims to extract key characteristic variables that reflect the link structure's ability to respond to external disturbances, characterizing the risk paths and critical characteristics of a link's transition from stable operation to an unstable state.

[0046] After obtaining the link stability characteristics, the system further screens and categorizes these characteristic variables, extracting those with a significant impact on link transmission capacity, coordination, or scheduling efficiency as secondary influencing factors. To ensure the representativeness and computational efficiency of these factors, the system also uses a feature selection algorithm to reduce the dimensionality of the link response variables, retaining only those variables that fluctuate significantly under environmental disturbances and significantly impact system coordination, ultimately forming a set of link-layer influencing factors.

[0047] S203. Construct an environmental pressure scenario for the new energy industry chain based on the node layer influencing factor set and the link layer influencing factor set; perform a climate environment fluctuation analysis on the node layer influencing factor set and the link layer influencing factor set to obtain the fluctuation characteristics of the new energy industry chain under the target environmental parameters; and set the environmental pressure scenario for the new energy industry chain based on the fluctuation characteristics.

[0048] In one embodiment, to accurately analyze the dynamic operating characteristics of the new energy industry chain under target environmental parameter perturbations, a multidimensional trajectory of its changes over historical time is constructed based on the extracted sets of node-layer and link-layer influencing factors. Specifically, each influencing factor is arranged by timestamp to form a multidimensional time series matrix. Local statistical features are extracted using a sliding time window, including metrics such as mean, standard deviation, skewness, kurtosis, and coefficient of variation, to characterize the underlying fluctuation trends under historical operating conditions.

[0049] Subsequently, to simulate the driving impact of changes in environmental parameters on the operation of the industrial chain, a climate fluctuation model was introduced to model the perturbations of the target environmental parameters. This model can be constructed based on national meteorological observation data, remote sensing monitoring data, and climate prediction model data (such as CMIP6, Coupled Model Intercomparison Project Phase 6). It uses the following three strategies to generate environmental perturbation sequences: First, a periodic perturbation model is constructed by extracting periodic fluctuations in parameters such as temperature and humidity using Fourier transforms. Second, a Monte Carlo simulation method is used to generate high-confidence extreme perturbation sequences using historical extreme weather sample sets. Third, a trend drift model is established to simulate long-term climate change by combining interannual trends with changes in the urban heat island effect.

[0050] After obtaining the environmental disturbance sequence, it is input as an exogenous variable, and coupled modeling techniques are used to simulate the disturbance sequence and the influencing factor sequence. Vector autoregression models, system dynamics models, or time series prediction models based on LSTM (Long Short-Term Memory) networks can be used to simulate the response of various influencing factors under different disturbance conditions. The simulation results are used to extract the performance changes of each node or link under the influence of disturbances, and further calculate their sensitivity distribution (such as the quantile of the change amplitude), response resilience (such as the disturbance recovery time), and stability interval (such as the probability interval of performance remaining within the normal fluctuation range).

[0051] Ultimately, this analysis revealed the overall fluctuation characteristics of the new energy supply chain under the context of target environmental parameter fluctuations. Specifically, these include the functional volatility at the node level, the changing trends in coupling strength at the link level, and the dynamic exposure of key bottleneck nodes and vulnerable links under various disturbance scenarios. These fluctuation characteristics not only serve as quantitative boundary conditions for constructing environmental stress scenarios but also provide data support for subsequent node-level real-time response testing and full-chain economic impact assessments.

[0052] In order to achieve a multi-dimensional and multi-scenario assessment of the operational response capability of the new energy industry chain under different climatic environmental disturbances, it is necessary to set environmental pressure scenarios based on the fluctuation characteristic data obtained above. Setting environmental pressure scenarios for the new energy industry chain according to the fluctuation characteristics may include the following steps: constructing an environmental pressure conduction model based on the fluctuation characteristics, the environmental pressure conduction model is used to characterize the pressure conduction path of the new energy industry chain under target environmental parameters; identifying target sensitive units of the new energy industry chain according to the environmental pressure conduction model, the target sensitive unit is the target industry chain node in the new energy industry chain whose stability does not meet the preset requirements; setting the environmental pressure intensity coefficient based on the target sensitive unit; setting the environmental pressure scenario according to the environmental pressure intensity coefficient.

[0053] In one embodiment, in order to achieve structured characterization of the operating status and response capability assessment of the new energy industry chain under the target environmental parameter fluctuation conditions, the system constructs an environmental pressure conduction model based on the obtained fluctuation characteristics to characterize the pressure conduction path of the new energy industry chain under the target environmental parameters, and accordingly identifies the target industry chain nodes whose stability does not meet the preset requirements as target sensitive units, and then sets the environmental pressure intensity coefficient and constructs the environmental pressure scenario to achieve response simulation and risk prediction of the industry chain under complex environmental disturbances.

[0054] Specifically, the system first relies on the existing industrial chain topology and its historical operational monitoring data, and combines the time series fluctuation characteristics of the node-layer influencing factor set and the link-layer influencing factor set to construct an environmental pressure transmission model. The pressure transmission model uses environmental disturbance factors as driving variables and maps their transmission paths to the operating status of each industrial chain node through multi-level coupling relationships, reflecting the directionality and intensity distribution of the impact of different disturbance sources on each structural unit within the system. In the pressure transmission model, environmental disturbances propagate to downstream nodes through link-layer coupling paths, causing node operating status deviations or functional degradation.

[0055] After the pressure conduction model is constructed, the system conducts a stability assessment on the state response of each node in the industrial chain during the disturbance conduction process. To achieve standardization and objectivity in stability judgment, the system pre-sets the judgment threshold of the stability assessment as a preset requirement. The preset requirements are formulated based on the statistical analysis of historical operating data, combined with the operating tolerance capabilities, industrial policy requirements and equipment technical specifications of various typical nodes in the new energy industry chain. Specifically, they include: the maximum allowable output deviation rate of the node per unit time, the maximum allowable fluctuation range of the operating parameters, the maximum tolerance threshold of the response recovery time, and the acceptable upper limit of the fault frequency, among other dimensional indicators. These indicators are obtained by clustering analysis and parameter fitting of the node behavior patterns in normal operating conditions in historical samples, and are solidified as the stability judgment benchmark for system operation after evaluation by industry experts and adjustment of policy constraints.

[0056] The system compares and analyzes each node's response data under simulated disturbance conditions against preset requirements. If a node exhibits a state deviation exceeding any of the above-prescribed stability thresholds over multiple consecutive disturbance cycles, its stability is determined to be non-compliant with the preset requirements. Such nodes are identified as target sensitive units, indicating operational vulnerabilities or response instability in the current environmental disturbance transmission path. They may become trigger points for systemic risks and therefore should be prioritized for environmental stress scenario construction.

[0057] After identifying a target sensitive unit, the system further calculates its environmental pressure intensity coefficient based on its topological position, structural role, and response characteristics in the environmental pressure transmission model. This coefficient quantifies the actual impact of a disturbance on that node. It comprehensively considers factors such as the disturbance input amplitude, the node's response amplitude, and recoverability, forming a quantitative expression of the structural unit's risk tolerance under disturbance-driven pressure.

[0058] Ultimately, the system sets environmental pressure scenarios based on the environmental pressure intensity coefficient, forming a set of scenario parameters encompassing the disturbance variable type, disturbance intensity, disturbance action range, and action time period. These environmental pressure scenarios serve as boundary input conditions for subsequent system simulation and response testing, simulating the operational state of the new energy industry chain under diverse environmental disturbances. This provides structured support for subsequent node-level response testing, risk assessment of target sensitive units, and quantification of regional economic impacts.

[0059] S204. Testing real-time industry chain data of the new energy industry chain under target environmental parameters in an environmental pressure scenario to obtain test data; In one embodiment, to achieve high-precision simulation and assessment of the operating status of the new energy industry chain under specific environmental stress scenarios, it is necessary to test the dynamic response of the new energy industry chain to target environmental parameter perturbations within the constructed environmental stress scenarios and obtain test data. The purpose of this testing is to systematically assess the performance fluctuations, instability trends, and system coordination capabilities of each node and link in the new energy industry chain under environmental perturbations of varying types and intensities, thereby providing a quantifiable basis for subsequent operational adaptability optimization, risk classification, and control strategy formulation.

[0060] During the specific implementation process, first, under the set environmental pressure scenario, a test model corresponding to the new energy industry chain structure is constructed. The test model can adopt the real-time mapping model of the industry chain built on the digital twin platform. The core of the real-time mapping model of the industry chain includes: Node state mapping module: Based on the node-level influencing factor set, it establishes the physical attributes (such as production capacity, energy consumption, inventory), logical attributes (such as scheduling strategy, upstream and downstream dependencies) of each node and its response function to environmental disturbances; Link dynamic transmission module: Based on the link layer influencing factor set, it simulates the transmission delay, interruption probability, loss rate, etc. of material flow, information flow, and energy flow under different environmental fluctuations; Perturbation injection module: Injects target environmental parameter disturbance sequences (such as sudden temperature rise, sudden drop in wind speed, unstable light, etc.) into the model in the form of dynamic variables to drive the testing process.

[0061] The real-time industry chain mapping model is initialized by calling historical measured data or real-time monitoring data, and dynamically collects real-time industry chain operation data during the test process, including but not limited to: Node output change rate (such as capacity deviation value per unit time); Changes in node energy efficiency (e.g., fluctuations in the ratio of energy consumption to output); Link transmission delay (e.g., the difference between the actual delay and the expected delay of raw material transmission); Failure probability of key nodes (e.g., frequency of triggering loss of function under disturbance); The overall synergy index of the system (such as calculated by the link flow rate matrix).

[0062] During testing, data is sampled at a fixed time step (e.g., every 10 minutes) to form a multidimensional time series test dataset. To enhance test accuracy and data credibility, the test platform can introduce a dynamic error correction mechanism, using an extended Kalman filter to correct the deviation between the model's predicted output and the observed value in real time, further improving the simulation results' fit.

[0063] After the test is completed, the collected test data will be structured and stored and categorized. The output format can be multi-field JSON or multi-dimensional CSV format, and each set of data will be labeled with environmental scenario labels and response level labels.

[0064] S205. Obtain the economic impact weight of the new energy industry chain on the regional economic development index; In one embodiment, to accurately evaluate the regional economic development index based on the dynamic operation of the new energy industry chain under environmental disturbances, it is necessary to obtain the economic impact weight of the new energy industry chain on the regional economic development index. This economic impact weight is used to quantify the contribution of each node and link in the industry chain to various regional economic indicators. It constitutes the weighting factor in the final calculation of the regional economic development index and is the core data foundation for establishing the mapping relationship between industrial disturbances and economic impacts.

[0065] To this end, we first construct a structural model of the regional economic development index based on the macroeconomic indicator system of the target region. The model can include the following economic target dimensions: regional GDP, industrial added value, industrial tax contribution, unit energy consumption output ratio, employment absorption capacity, green investment ratio, etc., which are unified into a set of regional economic indicators I = {I1, I2, ..., I n}. Among them, I i represents the i-th regional economic indicator, such as regional GDP, added value of new energy industries, unit energy consumption-to-output ratio, proportion of green investment, number of clean energy employees, regional fiscal revenue, etc. The selection of indicators should be based on the evaluation system published by national or local statistical departments to ensure consistency with the caliber of regional economic evaluation.

[0066] In order to obtain the influence weight of the new energy industry chain on the above economic indicators, the regional input-output analysis method is adopted. First, based on the national economic input-output table of the target region, the direct consumption coefficient matrix A between industries is constructed, where: A = [a ij ], where a ij represents the proportion of intermediate inputs used in the i-th industry in the total output of the j-th industry unit in the region; all a ij ∈[0,1], the matrix dimension is m×m, where m is the number of industries in the region. On this basis, calculate the complete demand coefficient matrix between industries (i.e., the Leontief inverse matrix): L = (EA) -1 , where E represents the m×m identity matrix; L = [l ij ], where l ij It means that when the final demand increases by one unit, the total output (including direct and indirect) of the i-th industry needs to increase in order to meet the demand; each column of the total demand coefficient matrix L represents the total pull effect of a certain industry on other industries. The new energy industry chain contains several industrial sectors corresponding to the regional input-output table. The set S = {s1, s2, ..., sn}, among which, j Represents the jth key node industry in the new energy industry chain (such as photovoltaic manufacturing, wind power equipment, energy storage, grid dispatching, etc.). Extract the row vector set corresponding to S in the complete demand coefficient matrix L to form the new energy industry chain's contribution matrix L to the overall regional economy. S Next, define the mapping matrix C between regional economic indicators and industry output = [c pi ], where c pi It represents the unit output contribution coefficient of the ith industry to the pth economic indicator. This coefficient can be obtained by fitting historical statistical data or set by policy guidelines. The dimension of C is n×m, where n is the number of economic indicators and m is the number of industries.

[0067] The driving effect of the new energy industry chain on the economic system S Multiplying it with the indicator mapping matrix C, we get the contribution vector V of the new energy industry chain to the regional economic indicators: in, is the total driving effect vector of each industrial node in the new energy industry chain (i.e. L S The column vector and V = {v1,v2,…,v n}, where v p Represents the relative contribution value of the new energy industry chain to the p-th regional economic indicator. Finally, the contribution vector V is normalized to obtain the economic impact weight vector W of the new energy industry chain on the regional economic development index: p=1,2,…,n, that is, W={w1,w2,…,w n}, Among them, w p represents the impact weight of the new energy industry chain on the pth regional economic indicator; n is the total number of regional economic indicators; the economic impact weight W will be used in the weighted calculation of the subsequent regional economic development index.

[0068] S206. Calculate the regional economic development index based on the test data and the economic impact weight to obtain an evaluation result of the regional economic development index.

[0069] Based on the test data, the node response index and link response index of the new energy industry chain under the target environmental parameters are calculated; the node response index and link response index are weighted to obtain the industry chain environmental adaptability index; the industry chain environmental adaptability index is corrected according to the pressure intensity coefficient to obtain the target industry chain environmental adaptability index; the regional economic development index is calculated based on the target industry chain environmental adaptability index and the economic impact weight.

[0070] In one embodiment, to achieve dynamic assessment and precise quantification of the regional economic development index, a regional economic development index calculation model adaptable to different environmental disturbance scenarios is constructed based on environmental stress test data and economic impact weights. The core of this model is to integrate the operational adaptability of the new energy industry chain under target environmental parameters with its contribution to various regional economic indicators, thereby outputting a regional economic development index evaluation result that is structurally responsive and economically sensitive.

[0071] During the specific implementation process, we first quantitatively analyze the response characteristics of the new energy industry chain under the target environmental parameter scenario based on the aforementioned test data. According to the multi-dimensional time series data output by the test model, the operating status parameters of each node and each link in the industry chain are extracted, such as node output deviation rate, energy efficiency fluctuation rate, link transmission interruption frequency, response delay, etc. Based on the above indicators, the node response index and link response index are constructed to respectively characterize the stability and coordination of the local structure of the industry chain under the disturbance of the target environmental parameters. Let the response index of the i-th node be: in, represents the response index of the i-th node; represents the theoretical output level of the i-th node under the benchmark environment; Represents the actual test output of the i-th node under the target environment parameters; the closer the response index is to 1, the more stable the node performance.

[0072] The calculation of the link response index is similar. Let the response index of the jth link be: in, represents the response index of the jth link; is the average transmission delay of the link under the benchmark environment; D j is the test delay of the link under the target environmental parameter conditions; ∈ is a constant (such as 0.001) to prevent the denominator from being zero; a larger value indicates a more stable link and a smaller transmission delay.

[0073] The environmental adaptability index of the new energy industry chain as a whole is obtained by weighted calculation of all node response indices and link response indices, which is expressed as: Among them, R chain represents the environmental adaptability index of the industrial chain; N is the total number of nodes, M is the total number of links; α, β∈[0,1] and α+β=1, α, β are the weights used to adjust the overall adaptability of nodes and links. The environmental adaptability index reflects the comprehensive operating performance of the entire industrial chain under the current environmental pressure.

[0074] Considering that the impact of the intensity of different environmental disturbances on the adaptability of the industrial chain has nonlinear characteristics, the pressure intensity coefficient is introduced to correct the environmental adaptability index of the industrial chain. Let the environmental pressure intensity coefficient be S p∈[0,1], which is determined by the environmental disturbance amplitude, duration and change rate. The final target industry chain environmental adaptability index is: R adj =R chain ·(1-S p ), where R adj It represents the environmental adaptability index of the industrial chain after correction of pressure intensity; when the environmental pressure intensity is greater (i.e. S p The closer it is to 1), the further the adaptability index of the industrial chain will be weakened, reflecting its actual resilience in extreme environments.

[0075] Finally, based on the target industry chain environmental adaptability index R adj The economic impact weight vector W = {w1,w2,…,w n}, perform weighted calculation on the regional economic indicator set to obtain the regional economic development index EDI: Among them, EDI is the final output regional economic development index; I p represents the standardized value of the p-th regional economic indicator, which can be normalized based on the historical average level or policy baseline; w p is the economic impact weight of the new energy industry chain on this indicator; R adj It plays a dynamic adjustment role, so that the index can truly reflect the actual contribution of the new energy industry chain to the regional economy under conditions of environmental disturbance.

[0076] Optional, in Figure 2 After step S206 of the illustrated embodiment, the following steps may be performed: Based on the test data, the risk index of the target sensitive unit is calculated; the risk level of the target sensitive unit is divided according to the risk index; based on the regional economic development index evaluation results and risk level, a regional economic development risk assessment report is generated.

[0077] In one embodiment, in order to realize the structural risk identification and operational stability assessment of the regional economic system under multi-dimensional environmental disturbance conditions, the system, on the basis of completing the construction of the environmental pressure scenario of the new energy industry chain, further calculates the risk index and classifies the risk level of the target industry chain nodes whose stability does not meet the preset requirements, i.e., the target sensitive units, based on the test data, and generates a regional economic development risk assessment report in combination with the regional economic development index evaluation results, thereby realizing a multi-level, full-link, and structured risk expression of the regional economic operation status.

[0078] During implementation, the system first acquires the response data of each target sensitive unit under disturbance conditions. This response data includes multi-dimensional operational indicators such as the rate of change of node output, degree of performance fluctuation, state recovery time, and coupling path interruption. Based on these indicators, the system constructs a risk index calculation model to characterize the level of operational uncertainty of each target sensitive unit under specific environmental disturbances. The risk index is an important quantitative indicator for measuring the adaptability of structural unit systems. A larger value indicates that the node will exhibit stronger production capacity fluctuations, greater state fluctuations, or more significant functional degradation under stress scenarios, which may in turn have a greater impact on the overall regional economic operation.

[0079] The risk index calculation model constructs a weighted aggregation function after normalizing multidimensional response parameters. Weights are assigned based on the relative importance of different indicators in overall system stability, achieving a unified quantitative expression of risk characteristics. The system ensures that this calculation process is consistent with the aforementioned stability requirements, ensuring logical consistency and response sensitivity of upstream and downstream risk identification data.

[0080] After calculating the risk index for all target sensitive units, the system maps each node's risk index to discrete risk level intervals based on a pre-defined risk grading model. Risk grading criteria can be determined based on the distribution of historical risk event data, the node's influence within the industrial chain structure, and the statistical quantile of the risk index, forming a relatively stable grading system. Each level corresponds to a different risk management strategy priority, and the resulting grading will serve as input for subsequent regional economic risk analysis.

[0081] Based on the risk levels of target sensitive units, the system further integrates these risk ratings with the regional economic development index. The regional economic development index reflects the overall economic structure, development vitality, and industrial support of a region, while the risk level reveals the operational vulnerability of key nodes in the new energy industry chain under specific scenarios. Through structural mapping relationships, the system structurally couples the operational risks of the industry chain with macroeconomic development indicators, identifying key risk paths or bottlenecks that may adversely affect the regional economic development index.

[0082] Ultimately, the system generates a regional economic development risk assessment report based on the results of this integrated analysis. This report includes an analysis of the regional economic development index and its influencing factors, the risk index and risk level distribution of target sensitive units, the identification of key risk nodes and links, an analysis of potential risk transmission pathways, and risk response recommendations for different scenarios. The report is output in a structured format, supporting graphical presentation and strategy output, to assist industry management agencies or investment entities in implementing zoning control, optimizing industrial structure, or making risk prevention and control decisions.
