[0002] Hydrogen energy is a crucial tool for building a new energy system and achieving "dual carbon" goals. Currently, the hydrogen energy industry is transitioning from demonstration applications to large-scale commercial development, while facing challenges such as regional homogeneous competition, resource and market mismatch, and insufficient supply chain synergy.

Figure 2 The illustration shows a flowchart of a multi-dimensional construction method for a hydrogen energy industry development index provided in this application embodiment; Figure 3 A schematic diagram of the structure of a hydrogen energy industry assessment device based on a hydrogen energy industry development index provided in an embodiment of this application is shown. Figure 4 A schematic diagram of the device structure of a computer device provided in an embodiment of this application is shown. Detailed Implementation

[0022] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0023] In this embodiment, Figure 1This application provides a schematic flowchart of a hydrogen energy industry assessment method based on a hydrogen energy industry development index, as illustrated in an embodiment of this application. Figure 1 As shown, the method includes: Step S101: Obtain the evaluation index system of the constructed hydrogen energy industry development index, wherein the evaluation index system includes at least: multiple secondary indicators.

[0024] In the technical solution provided in step S101 of this application, an evaluation index system for the hydrogen energy industry development index can be obtained. This evaluation index system can include a four-layer architecture, consisting of a comprehensive index, sub-indices, primary indicators, and secondary indicators. This evaluation index system for the hydrogen energy industry development index can be referred to as the hydrogen energy industry development index evaluation system.

[0025] Optionally, multiple secondary indicators can include the overall scale of hydrogen production and consumption, the scale of hydrogen output value, the cost of hydrogen production from renewable energy, the comprehensive competitiveness of hydrogen production from renewable energy, the number of first-of-its-kind hydrogen energy equipment in the energy sector, and the number of hydrogen-related patents, etc. It should be noted that the secondary indicators here are only examples and are not specifically limited.

[0026] For example, a hierarchical indicator system can be adopted to construct a four-layer structure that includes a comprehensive index, sub-indices, primary indicators, and secondary indicators, in order to facilitate subsequent assessment of the development level of the hydrogen energy industry in the target region.

[0027] Step S102: Dimensionless processing is performed on the indicator data of multiple secondary indicators to obtain multiple efficacy scores, whereby the efficacy scores are used to evaluate the indicator data of the secondary indicators.

[0028] In the technical solution provided in step S102 of this application, after obtaining multiple secondary indicators, an exponential efficacy function is used to perform dimensionless processing on the indicator data of multiple secondary indicators in order to obtain multiple efficacy scores.

[0029] For example, when the secondary indicators obtained are the number of hydrogen-related patents and the cost of hydrogen production from renewable energy, they cannot be directly calculated because the units of the two are different. They need to be dimensionless processed by an exponential efficacy function to obtain the efficacy score of each secondary indicator in order to eliminate the influence of dimensions.

[0030] It should be noted that this is only a preferred implementation method for obtaining multiple efficacy scores, and the process and method for obtaining multiple efficacy scores are not specifically limited. As long as the indicator data of multiple secondary indicators are dimensionless processed to obtain multiple efficacy scores, the process and method are within the protection scope of this application, and will not be listed here.

[0031] Step S103: Using the Delphi method, obtain the index weight of each index in the evaluation index system, and determine the evaluation value of the hydrogen energy industry development index based on the index weight of each index and multiple efficacy scores.

[0032] In the technical solution provided in step S103 of this application, the Delphi method is used to obtain the index weight of each index in the evaluation index system, and then the evaluation value of the hydrogen energy industry development index is determined based on the index weight of each index and multiple efficacy scores obtained above.

[0033] Optionally, the indicator weights can be called weight coefficients, and are determined by... The evaluation value of the hydrogen energy industry development index can be expressed as follows: To express.

[0034] Optionally, the Delphi method is used to scientifically determine the weight coefficients of indicators at each level through multiple rounds of expert consultation and feedback, so that the weight coefficients can be dynamically adjusted with the stage of industrial development and policy orientation, and the top-level equal weighting ensures the balance of the evaluation indicator system.

[0035] For example, using the Delphi method, experts conducted multiple rounds of scoring to determine the weighting coefficients for the secondary indicators "number of hydrogen-related patents" and "number of first-of-its-kind hydrogen energy equipment in the energy sector," assigning them 0.6 and 0.4 respectively. Assuming that the dimensionless efficiency scores for these two indicators for a certain region are 85 and 75 respectively, the score for the composite primary indicator "technology transfer" would be 84. Similarly, the scores for other primary indicators under this sub-index are calculated and weighted to form the sub-index "innovation-driven capability." Finally, the weighted sum of the five sub-indices yields the comprehensive evaluation value of the hydrogen energy industry development index.

[0036] It should be noted that this is only a preferred implementation method for determining the evaluation value of the hydrogen energy industry development index. The method and process for determining the evaluation value of the hydrogen energy industry development index are not specifically limited. As long as the evaluation value of the hydrogen energy industry development index is based on the indicator weight of each indicator and multiple efficacy scores, the method and process for determining the evaluation value of the hydrogen energy industry development index are within the scope of protection of this application, and will not be listed here.

[0037] Step S104: Based on the evaluation value of the hydrogen energy industry development index, assess the development level of the hydrogen energy industry in the target region and obtain the assessment results.

[0038] In the technical solution provided in step S104 of this application, the evaluation value of the hydrogen energy industry development index obtained in the above steps can be used to assess the development level of the hydrogen energy industry in the target region, thereby obtaining the assessment result. The target region can be a pre-defined region, such as North China or Southwest China.

[0039] For example, the national hydrogen energy industry development index for a certain year was calculated to be 73.68, while the index for North China was 85.04 and for Southwest China it was 66.02. Based on this assessment, North China's score far exceeded the baseline, and the assessment result was "leading development, belonging to the first tier of national engines"; Southwest China's score was below the baseline, and the assessment result was "lagging development, belonging to the second tier".

[0040] Furthermore, based on the calculated comprehensive index and sub-index evaluation values, the industrial development level of the target region is assessed. The hydrogen energy industry development index of different regions in the same period is compared and ranked horizontally, and the hydrogen energy industry development index of the same region in different periods is analyzed vertically for dynamic changes. Furthermore, by analyzing the scores of sub-indices and primary indicators, the advantages and disadvantages of hydrogen energy industry development are identified, providing a quantitative reference for market investment.

[0041] It is understood that this is only a preferred implementation method for obtaining the assessment results, and the method and process of obtaining the assessment results are not specifically limited. As long as the assessment of the hydrogen energy industry development level of the target region is based on the evaluation value of the hydrogen energy industry development index, the process and method of obtaining the assessment results are within the protection scope of this application, and will not be listed here.

[0042] In the technical solution provided in steps S101 to S104 of this application, an evaluation index system for the hydrogen energy industry development index is first established. This evaluation index system includes at least multiple secondary indicators. Then, the multiple secondary indicators are dimensionless to obtain the efficacy score of each secondary indicator. Next, the weight of each indicator in the evaluation index system is determined using the Delphi method. Finally, the evaluation value of the hydrogen energy industry development index is calculated using the weight of each indicator and the multiple efficacy scores. Based on the hydrogen energy industry development index, the assessment of the hydrogen energy industry development level in the target region is completed. In other words, this application, by establishing a complete evaluation index system, dimensionlessly processing the indicator data of multiple secondary indicators in the system, and scientifically determining the indicator weights using the Delphi method, compensates for the deficiencies of traditional evaluation methods, such as incomplete dimensions, poor algorithm adaptability, and unreasonable weight settings. This effectively improves the accuracy of the assessment, solves the problem of low accuracy in the assessment of the hydrogen energy industry, and achieves the technical effect of improving the accuracy of the hydrogen energy industry assessment.

[0043] The method described in this embodiment will be further described below.

[0044] As an optional implementation method, the evaluation index system may include at least: multiple primary indicators, multiple sub-indices, and a hydrogen energy industry development index. The primary indicators consist of one secondary indicator, or at least two secondary indicators, the sub-indices consist of at least three primary indicators, and the hydrogen energy industry development index consists of at least five sub-indices.

[0045] In this embodiment, in addition to the evaluation index system including multiple secondary indicators, the evaluation index system also includes at least: multiple primary indicators, multiple sub-indices, and a hydrogen energy industry development index. The hydrogen energy industry development index can be referred to as a comprehensive index.

[0052] Optionally, as shown in Table 1, the overall scale of hydrogen production and consumption and the scale of hydrogen output value, which are secondary indicators, can constitute the primary indicator of market size; the cost of hydrogen production from renewable energy and the comprehensive competitiveness of hydrogen production from renewable energy, which are secondary indicators, can constitute the primary indicator of techno-economics; and the capacity scale of electrolyzers and fuel cells, which are secondary indicators, can constitute the primary indicator of equipment manufacturing. The primary indicators obtained above—market size, techno-economics, and equipment manufacturing—constitute the industrial development foundation for the sub-indices. Using the above method, the other four sub-indices can be determined, as shown in Table 1, and will not be elaborated further here. After obtaining the five sub-indices, the comprehensive index can be determined.

[0053] For example, a hierarchical index structure is adopted, constructing a four-layer framework including a comprehensive index, sub-indices, primary indicators, and secondary indicators. The comprehensive index is the China Hydrogen Energy Industry Development Index. The sub-indices include five core dimensions: Industrial Development Foundation Sub-index D1, Innovation-Driven Capability Sub-index D2, Application and Promotion Level Sub-index D3, Infrastructure Construction Sub-index D4, and Factor Support and Guarantee Sub-index D5. Each sub-index has several primary indicators, and the primary indicators are further subdivided into corresponding secondary indicators, as shown in Table 1.

[0054] As an optional implementation method, the indicator data of multiple secondary indicators are dimensionless processed using the following formula to obtain multiple efficacy scores, including:

[0055] Where j represents the index of the sub-index; k represents the index of the primary index; and z represents the index of the secondary index. Used to represent the effectiveness score of the indicator data corresponding to the z-th secondary indicator under the k-th primary indicator under the j-th sub-index; Used to represent the actual value of the indicator data corresponding to the z-th secondary indicator under the k-th primary indicator under the j-th sub-index; Used to represent the first allowable value; A is used to represent the second allowable value, which is greater than the first allowable value; B is used to represent the preset parameter; and C is used to represent the preset function.

[0056] In this embodiment, an exponential power function is used to perform dimensionless processing on each secondary indicator, and the calculation formula is as follows:

[0057] in, This refers to the evaluation value of a single evaluation indicator within the secondary indicators, i.e., the effectiveness score. This refers to the actual value of a single indicator; This is the first permissible value, and the first permissible value can be called the unpermissible value; The second allowable value, also known as the satisfactory value or the rigid allowable value, is used to represent the upper and lower limits of the cross-section at a fixed time, respectively. The undetermined parameters A and B are determined through critical points.

[0058] Optionally, when the value is not allowed ( When a score of 60 is set, it can be used to indicate that the hydrogen energy industry in a region is in its initial or nascent stage. When a certain indicator reaches the lowest level in the region (or the whole country) in the base year, its development level is considered to have just reached the acceptable "unacceptable" state, that is, the basic threshold.

[0059] Optionally, when the allowable value ( When the score is set to 100, for leading regions in the hydrogen energy industry, some indicator values ​​may be at the top level domestically. This is used to identify the best performance of that indicator domestically in the base year, aiming to incentivize other regions to emulate the benchmark while reserving room for growth in subsequent years' longitudinal comparisons. This indicates that x has reached an unacceptable value. Based on the linear power function, we set... ,but ;when This indicates that x has reached the allowable value. Based on the linear function, we set... ,have Parameter combinations ( , This allows the exponential efficiency function to maintain high sensitivity in the low-value region (close to the unacceptable value) of hydrogen energy industry indicators, enabling it to sensitively capture breakthrough progress in the industry from scratch; while in the high-value region (close to the barely permissible value), the growth rate gradually slows down, which conforms to the nonlinear law of diminishing marginal contribution of hydrogen energy industry indicators after reaching a certain scale. This aligns with the current specific stage characteristic of the hydrogen energy industry "shifting from technology verification to large-scale development." Therefore, the exponential efficiency function can be written as follows: .

[0060] In the embodiments of this application, the unacceptable value ( ) and the allowable value ( The value is determined based on cross-sectional data from a fixed base year (such as 2024 in this embodiment). For subsequent years or other regions, when the actual value of a certain indicator exceeds the threshold range set for the base year, it is still directly substituted into the exponential efficacy function formula for calculation, and the calculated efficacy score is obtained. It can be below 60 or above 100, and has a clear industrial economic meaning. That is, when When this occurs, it indicates that the actual level of this indicator in the region (or during this period) has surpassed the best domestic level of the baseline year, reflecting a substantial breakthrough in industrial development. The successful surpassing of the baseline year is a healthy signal of industrial progress. If the actual level of the indicator in the region (or during that period) is lower than the worst level in the country in the baseline year, then the region is experiencing development lag or regression, which requires attention.

[0061] As an optional implementation method, the evaluation value of the hydrogen energy industry development index is determined based on the indicator weight of each indicator and multiple efficacy scores, including: determining the evaluation value of multiple primary indicators based on multiple efficacy scores and the indicator weights of the corresponding secondary indicators; determining the evaluation value of multiple sub-indices based on the evaluation value of the multiple primary indicators and the indicator weights corresponding to the multiple primary indicators; and determining the evaluation value of the hydrogen energy industry development index based on the evaluation value of the multiple sub-indices and the indicator weights corresponding to the multiple sub-indices.

[0062] In this embodiment, the evaluation values ​​of multiple primary indicators can be determined based on multiple efficacy scores and the corresponding weights of multiple secondary indicators. Then, based on the evaluation values ​​of the multiple primary indicators and the corresponding weights of the multiple primary indicators, the evaluation values ​​of multiple sub-indices are determined. Finally, based on the evaluation values ​​of the multiple sub-indices and the corresponding weights of the multiple sub-indices, the evaluation value of the hydrogen energy industry development index is determined.

[0063] Optionally, based on multiple efficacy scores and the corresponding weights of multiple secondary indicators, the evaluation values ​​of multiple primary indicators are determined, including: weighted summation of multiple efficacy scores of multiple secondary indicators and the corresponding weights of multiple secondary indicators to obtain multiple first sums; summation of the weights of multiple secondary indicators to obtain multiple second sums; and determination of the evaluation values ​​of multiple primary indicators based on the multiple first sums and the multiple second sums.

[0066] As an optional implementation method, the evaluation values ​​of multiple primary indicators are determined based on multiple efficacy scores and the corresponding weights of secondary indicators using the following formula, including:

[0067] in, Used to represent the evaluation value of the indicator data corresponding to the kth primary indicator under the jth sub-index; The indicator weight is used to represent the indicator data corresponding to the z-th secondary indicator under the k-th primary indicator under the j-th sub-index; This is used to indicate the number of secondary indicators contained in the k-th primary indicator under the j-th sub-index.

[0068] In this embodiment, the evaluation values ​​of multiple primary indicators are obtained by calculating multiple efficacy scores and the corresponding secondary indicator weights using the following formula, including:

[0069] in, This is used to indicate the number of secondary indicators contained in the k-th primary indicator under the j-th sub-index, such as 1, 2, 3, etc.

[0070] For example, the process of synthesizing secondary indicators into primary indicators is as follows: The secondary indicator "Technology Transfer" under the sub-index "Innovation-Driven Capability" Based on the number of hydrogen-related patents And the number of first-of-its-kind hydrogen energy equipment in the energy sector. The two secondary indicators are combined, resulting in weights of 0.036 and 0.024 respectively. Therefore, the evaluation value for the primary indicator's achievement transformation is: .

[0071] As an optional implementation method, the evaluation values ​​of multiple sub-indices are determined based on the evaluation values ​​of multiple primary indicators and the indicator weights corresponding to the primary indicators using the following formula, including:

[0072] in, Used to represent the evaluation value of the indicator data corresponding to the j-th sub-index; The indicator weight used to represent the k-th primary indicator; This is used to indicate the number of primary indicators contained in the j-th sub-index.

[0073] In this embodiment, the evaluation values ​​of multiple primary indicators and their corresponding indicator weights are calculated using the following formulas to obtain the evaluation values ​​of multiple sub-indices, including:

[0074] in, This is used to indicate the number of primary indicators contained in the j-th sub-index, for example, 3. It should be noted that this is only an example illustrating the number of primary indicators contained in a single sub-index.

[0075] For example, the process of synthesizing sub-indices from primary indicators is as follows: Sub-index: Innovation-driven capability From "technology transfer" "Standard guidance" "Innovation Ecosystem" If the three primary indicators are combined, and their weights are 0.06, 0.08, and 0.06 respectively, then: .

[0076] As an optional implementation method, the evaluation value of the hydrogen energy industry development index is determined based on the evaluation values ​​of multiple sub-indices and the indicator weights corresponding to the sub-indices, using the following formula:

[0077] in, Evaluation values ​​used to represent the development index of the hydrogen energy industry; The index weight is used to represent the j-th sub-index; n represents the number of sub-indices.

[0078] In this embodiment, the evaluation value of the hydrogen energy industry development index is obtained by weighted summation of the evaluation values ​​based on multiple sub-indices and the indicator weights corresponding to the sub-indices using the following formula:

[0079] Here, n represents the number of sub-indices, for example, 5. Only the number of sub-indices is illustrated here.

[0080] Optionally, the Delphi method is used to set the weights of each indicator. Specifically, this includes: inviting experts in the hydrogen energy industry to assess the relative importance of indicators at each level; collecting expert opinions and conducting multiple rounds of feedback and adjustments until consensus is reached. In the first round of open consultation, a complete hierarchical indicator system (see Table 1) is provided to experts. Experts are asked to independently compare the relative importance of each indicator at the same level pairwise and provide suggested weight values ​​(summing 1 or 100%). In the second round of feedback and re-evaluation, the first round of questionnaires is collected, and the average, median, and interquartile range of the weight assignments given by all experts for each indicator are calculated. The statistical results, along with the original assignment tables from the first round, are fed back to each expert. Experts are asked to refer to the group statistical results and reconsider and revise their weight assignments. In the third round of stability testing, the second round is repeated. Once consensus is reached among experts, the consultation is stopped, and the arithmetic mean of the final round of expert opinions is taken as the final weight coefficient for each indicator. Based on the "barrel effect" theory of industrial systems theory, the five sub-indices are weighted equally when calculating the total index. This aims to emphasize that the hydrogen energy industry needs to develop in a coordinated manner across five dimensions: "foundation, driving force, performance, support, and environment." In other words, each sub-index has equal weight, avoiding the overemphasis of a single dimension from masking the shortcomings of other dimensions, and guiding the industry toward comprehensive and balanced development.

[0081] For example, the five sub-indices are weighted equally when evaluating the Synthetic Hydrogen Energy Industry Development Composite Index (HIDI), meaning each sub-index has an equal weight. The calculation method is a weighted arithmetic average, with each sub-index having a weight coefficient of 1. The calculation method is as follows: .

[0082] For another example, the weighted arithmetic mean composite model is used to calculate the index, starting from the bottom-level secondary indicators and working upwards step by step to obtain the evaluation value of the comprehensive index.

[0083] In this embodiment, an evaluation index system for the development of the hydrogen energy industry is first established, and this evaluation index system includes at least multiple secondary indicators. Then, the multiple secondary indicators are dimensionless to obtain the efficacy score of each secondary indicator. Next, the weight of each indicator in the evaluation index system is determined using the Delphi method. Finally, the evaluation value of the hydrogen energy industry development index is calculated using the weight of each indicator and the multiple efficacy scores. Based on the hydrogen energy industry development index, the assessment of the hydrogen energy industry development level in the target region is completed. In other words, this application, by establishing a complete evaluation index system, dimensionlessly processing the indicator data of multiple secondary indicators in the system, and scientifically determining the indicator weights using the Delphi method, compensates for the shortcomings of traditional evaluation methods, such as incomplete dimensions, poor algorithm adaptability, and unreasonable weight settings. This effectively improves the accuracy of the assessment, solves the problem of low accuracy in the assessment of the hydrogen energy industry, and achieves the technical effect of improving the accuracy of the hydrogen energy industry assessment.

[0084] Furthermore, as a refinement and extension of the specific implementation methods of the above embodiments, in order to fully explain the specific implementation process of this embodiment, Figure 2 This application provides a flowchart illustrating a multi-dimensional construction method for a hydrogen energy industry development index, as illustrated in an embodiment of this application. Figure 2 As shown, the method includes: Step S201: Collect raw data of indicators for each region in the target year.

[0085] In this embodiment, the hydrogen energy industry development index of my country and seven major regions (North China, Northeast China, East China, Central China, South China, Southwest China and Northwest China) is calculated with 2024 as the base year.

[0086] Optionally, raw data for the whole country and various regions in 2024 can be collected based on the constructed evaluation index system. All data are derived from publicly available sources, such as industry research reports and publicly available corporate information.

[0087] Step S202: Using an exponential efficacy function, calculate the efficacy scores of the secondary indicators in the evaluation index system.

[0088] In this embodiment, an exponential efficacy function formula is used to calculate the efficacy score of each secondary indicator:

[0089] Using 2024 as the base year, for positive secondary indicators, the maximum value of the indicator data from the seven major regions is taken as the rigid allowable value. The minimum value is considered an unacceptable value. For the inverse secondary index, the minimum value is taken as the rigid allowable value. The maximum value is considered an unacceptable value. For example, regarding the positive indicator of "number of hydrogen-related patents," the highest value among the seven regions in 2024 came from East China, denoted as [missing information]. The minimum value comes from the southwest region, let it be... Taking the number of hydrogen-related patents in North China as an example, let x = 8500. =1200 pieces, =9800 pieces, and the efficacy score d=87.36 points was obtained by substituting into the formula.

[0090] Step S203: Based on the weights of multiple indicators, the index is synthesized using a weighted arithmetic mean synthesis model. The synthesis proceeds from the bottom-level secondary indicators upwards to obtain the evaluation value of the comprehensive index.

[0091] In this embodiment, the Delphi method is adopted, and experts in the hydrogen energy industry are invited to provide their opinions to determine the weights of indicators at each level. Specifically, for the China Hydrogen Energy Industry Development Index, the five sub-indices of industrial development foundation, innovation-driven capability, application and promotion level, infrastructure construction, and factor support guarantee are given equal weight in the calculation of the total index. This avoids the evaluation imbalance caused by excessive weighting of a single dimension, accurately reflects the development logic of the industry requiring multi-dimensional coordinated advancement, and is consistent with the current stage characteristics of the comprehensive development of the hydrogen energy industry.

[0092] Furthermore, a weighted arithmetic mean composite model is used to calculate the index, starting from the bottom-level secondary indicators and working upwards step by step to obtain the final evaluation value of the comprehensive index.

[0093] Step S204: Based on the calculated evaluation values ​​of the comprehensive index and sub-indices, the industrial development level of the target region is assessed.

[0094] In this embodiment, the calculated comprehensive index (HIDI) for the development of the national hydrogen energy industry in 2024 was 73.68. The ranking of the seven major regions was as follows: North China (85.04), Northwest China (74.30), East China (73.14), South China (70.86), Northeast China (70.50), Central China (66.43), and Southwest China (66.02). my country's regional development shows a significant divergence. From an overall perspective, North China (85.04) and Northwest China (74.30) constitute the first tier of development, with North China leading the national hydrogen energy industry with an absolute advantage exceeding the benchmark by 13.6%. Meanwhile, East China, South China, Northeast China, Central China, and Southwest China form the second tier, falling below the benchmark. The maximum score difference between regions reached 19.02, indicating a significant unbalanced development trend in the hydrogen energy industry across regions.

[0095] In this embodiment, an evaluation index system for the development of the hydrogen energy industry is first established, and this evaluation index system includes at least multiple secondary indicators. Then, the multiple secondary indicators are dimensionless to obtain the efficacy score of each secondary indicator. Next, the weight of each indicator in the evaluation index system is determined using the Delphi method. Finally, the evaluation value of the hydrogen energy industry development index is calculated using the weight of each indicator and the multiple efficacy scores. Based on the hydrogen energy industry development index, the assessment of the hydrogen energy industry development level in the target region is completed. In other words, this application, by establishing a complete evaluation index system, dimensionlessly processing the indicator data of multiple secondary indicators in the system, and scientifically determining the indicator weights using the Delphi method, compensates for the shortcomings of traditional evaluation methods, such as incomplete dimensions, poor algorithm adaptability, and unreasonable weight settings. This effectively improves the accuracy of the assessment, solves the problem of low accuracy in the assessment of the hydrogen energy industry, and achieves the technical effect of improving the accuracy of the hydrogen energy industry assessment.
