Background Technology

[0002] The supply and demand matching of scientific and technological achievements aims to match scientific and technological achievements in the research stage with project development, engineering construction or industrial needs, so as to realize the transformation and application of scientific and technological achievements.

[0003] Existing supply-demand matching schemes focus on comparing technical parameters at the technical level to match results with demand. They only consider the technical aspects and ignore influencing factors such as policies and energy markets. The evaluation dimensions are too simplistic, which can easily lead to recommended scientific and technological achievements not meeting policy regulations or market profit requirements. Furthermore, existing supply-demand matching schemes extract explicit parameters from demand documents for matching, focusing only on the obvious demand and not considering the internal implicit relationships of demand. This results in the parameters of demand and results not being accurately aligned, leading to low matching accuracy. Summary of the Invention

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As an example, the supply and demand matching of scientific and technological achievements aims to match scientific and technological achievements in the research stage with project development, engineering construction or industrial needs, so as to realize the transformation and application of scientific and technological achievements.

[0025] Existing supply-demand matching schemes focus on comparing technical parameters at the technical level to match results with demand. They only consider the technical aspects and ignore influencing factors such as policies and energy markets. The evaluation dimensions are too simplistic, which can easily lead to recommended scientific and technological achievements not meeting policy regulations or market profit requirements. Furthermore, existing supply-demand matching schemes extract explicit parameters from demand documents for matching, focusing only on the obvious demand and not considering the internal implicit relationships of demand. This results in the parameters of demand and results not being accurately aligned, leading to low matching accuracy.

[0026] To address this, this application obtains the engineering construction needs and candidate scientific and technological achievements corresponding to the construction project; it obtains technical, policy, and market dimension indicators of the candidate scientific and technological achievements to construct a multi-dimensional profile of the candidate scientific and technological achievements; it obtains explicit and implicit parameters of the engineering construction needs to construct a multi-dimensional profile of the engineering construction needs; based on the multi-dimensional profile of the achievements and the multi-dimensional profile of the needs, it calculates the technical compatibility, policy impact, and market benefit between the candidate scientific and technological achievements and the engineering construction needs; and it determines the target scientific and technological achievements corresponding to the engineering construction needs from the candidate scientific and technological achievements based on the technical compatibility, policy impact, and market benefit. This application's embodiments, by constructing a multi-dimensional profile of scientific and technological achievements corresponding to technology, policy, and market, and a multi-dimensional profile of engineering construction needs corresponding to explicit and implicit needs, enable the recommended scientific and technological achievements to meet the needs of multiple levels of technology, policy, and market, and transform implicit needs into quantifiable indicators, effectively improving the matching accuracy between needs and achievements. Reference Figure 1 The diagram illustrates a flowchart of a supply and demand matching method for scientific and technological achievements provided in an embodiment of this application, which may specifically include the following steps: Step 101: Obtain the engineering construction requirements and candidate scientific and technological achievements corresponding to the construction project; In this embodiment, the engineering construction requirements and candidate scientific and technological achievements are first obtained. Engineering construction requirements can be understood as the demand information for an engineering project, such as the requirement documents or project plans for clean energy projects like building a photovoltaic power station, constructing a pumped storage power station, or waterproofing the foundation pit of a pumped storage power station. Candidate scientific and technological achievements are multiple technical solutions to be matched; these can also be called technological achievements, such as high-altitude construction technology or hydropower seepage prevention technology. For example, the system receives the project requirement documents uploaded by the demand party and obtains technical documents for multiple scientific and technological achievements from a scientific and technological achievements database. Subsequently, supply and demand matching is performed based on the requirement documents and technical documents to promote the transformation of scientific and technological achievements.

[0027] Step 102: Obtain the technical dimension indicators, policy dimension indicators, and market dimension indicators of the candidate scientific and technological achievements, and construct a multi-dimensional achievement profile of the candidate scientific and technological achievements based on the technical dimension indicators, policy dimension indicators, and market dimension indicators; In this embodiment of the application, a multi-dimensional profile of each candidate scientific and technological achievement is constructed. The multi-dimensional profile consists of technical, policy and market indicators. The scientific and technological achievements are evaluated through different indicators to fully understand the value of the candidate scientific and technological achievements, which helps to recommend scientific and technological achievements that meet the needs of multiple levels such as technology, policy and market.

[0028] Step 103: Obtain the explicit parameters and implicit indicators of the project construction requirements, and construct a multi-dimensional requirement profile of the project construction requirements based on the explicit parameters and implicit indicators; In this embodiment, explicit requirements from the engineering construction needs are extracted, such as installed capacity and construction period explicitly recorded in the requirements document. Vague requirements are also identified and quantified into calculable indicators, such as "achieving zero-carbon construction" corresponding to carbon emissions during the construction period, and "efficient operation of pumped storage power stations" corresponding to energy conversion efficiency. Then, based on the explicit parameters corresponding to the explicit requirements in the construction project and the implicit indicators quantified from the implicit requirements, a multi-dimensional requirement profile of the engineering construction needs is constructed. This embodiment, by constructing a multi-dimensional requirement profile of the engineering construction needs, achieves a comprehensive understanding of the construction project's requirements, which helps in the accurate matching of subsequent requirements and outcomes.

[0029] Step 104: Based on the multi-dimensional achievement profile and the multi-dimensional demand profile, calculate the technical compatibility, policy impact, and market benefit between the candidate scientific and technological achievements and the engineering construction needs. In this embodiment, the multi-dimensional results of each candidate scientific and technological achievement are matched with the multi-dimensional demand profile of engineering construction needs to determine the technical compatibility, policy impact, and market benefit between the candidate scientific and technological achievements and engineering construction needs. The technical compatibility is the degree of fit between the technical parameters of the scientific and technological achievement and the technical requirements of the construction project, reflecting the extent to which the scientific and technological achievement meets the engineering technical requirements at the technical level. The policy impact is the degree of fit between the scientific and technological achievement and relevant policies, used to characterize the policy dividends that can be brought by adopting the scientific and technological achievement and whether it complies with regulations. The market benefit is the expected benefit when the scientific and technological achievement is applied to the construction project. Thus, through the technical compatibility, policy impact, and market benefit, the degree of matching between the scientific and technological achievement and engineering construction needs at multiple levels of technology, policy, and market can be intuitively obtained.

[0030] Step 105: Based on the technology adaptability, policy impact, and market profitability, determine the target scientific and technological achievement corresponding to the engineering construction needs from the candidate scientific and technological achievements.

[0031] In this embodiment, considering the technological compatibility, policy impact, and market profitability between candidate scientific and technological achievements and engineering construction needs, target scientific and technological achievements that meet engineering construction needs are recommended. As an example, based on the technological compatibility, policy impact, and market profitability of each candidate scientific and technological achievement with engineering construction needs, the recommendation priority of each candidate scientific and technological achievement is determined. A list of target scientific and technological achievements is then output according to the recommendation priority. Based on this list, the requester can intuitively understand the matching degree between each candidate scientific and technological achievement and the engineering construction needs, thereby accurately selecting target scientific and technological achievements that meet multi-level requirements.

[0032] In this embodiment of the application, by constructing a multi-dimensional profile of scientific and technological achievements corresponding to technology, policy, and market, and a multi-dimensional profile of engineering construction needs corresponding to explicit and implicit needs, the recommended scientific and technological achievements can meet the needs of multiple levels of technology, policy, and market, and the implicit needs can be transformed into quantifiable indicators, which effectively improves the matching accuracy between needs and achievements.

[0033] In some feasible implementations, the technological dimension indicators include at least technology maturity level, cross-domain reusability, and technological parameters; the policy dimension indicators include at least dual-carbon compatibility, policy matching degree, and subsidy amount; and the market dimension indicators include at least industrialization cost, investment payback period, and market penetration rate. The acquisition of the technological, policy, and market dimension indicators for the candidate scientific and technological achievements includes: The technology maturity of the candidate scientific and technological achievements is evaluated to obtain the technology maturity level of the candidate scientific and technological achievements. Obtain the industry chain knowledge graph corresponding to the candidate scientific and technological achievements, and analyze the candidate scientific and technological achievements based on the industry chain knowledge graph to obtain the cross-domain reusability of the candidate scientific and technological achievements; Extract the technical parameters from the candidate scientific and technological achievements; Obtain policy information and analyze the policy information and the candidate scientific and technological achievements to obtain the dual-carbon fit, policy matching degree and subsidy amount of the candidate scientific and technological achievements; Obtain market data and predict the candidate scientific and technological achievements based on the market data to obtain the industrialization cost, investment payback period and market penetration rate of the candidate scientific and technological achievements.

[0034] In this application embodiment, the multi-dimensional profile of candidate scientific and technological achievements includes three types of indicators, including but not limited to the technology maturity level, cross-domain reusability and technical parameters of the corresponding technology dimension, the dual-carbon fit, policy matching degree and subsidy amount of the corresponding policy dimension, and the industrialization cost, investment payback period and market penetration rate of the corresponding market dimension.

[0035] Regarding the technical dimension indicators, the Technology Readiness Level (TRL) characterizes the technological readiness of scientific and technological achievements. The TRL level is obtained by evaluating the TRL of candidate scientific and technological achievements. For example, the internationally accepted TRL 1-9 standard is used to evaluate candidate scientific and technological achievements and obtain their TRL levels. TRL 1-3 indicates that the scientific and technological achievement is in the basic research stage (i.e., the laboratory stage), TRL 4-6 indicates that the scientific and technological achievement is in the technology development stage (i.e., the prototype verification stage), and TRL 7-9 indicates that the scientific and technological achievement is in the engineering application stage (i.e., the industrialization deployment stage). Cross-domain reusability characterizes the adaptability of the scientific and technological achievement to other fields. The scientific and technological achievement is analyzed using a supply chain knowledge graph to calculate its adaptability score or level for application to the target field. For example, the cross-domain reusability level of applying hydropower seepage prevention technology to pumped storage power station seepage prevention is high. Technical parameters are the key performance indicators of the scientific and technological achievement, such as efficiency and power. For example, technical parameters can be extracted from the requirements document using natural language processing technology.

[0036] Regarding policy-related indicators, the carbon-coherence ratio refers to the degree of alignment between scientific and technological achievements and "carbon-coherence" policies. For example, the annual carbon emission reduction and carbon emission reduction cost of scientific and technological achievements can be calculated, and then the contribution of scientific and technological achievements to "carbon-coherence" policies can be determined based on the annual carbon emission reduction and carbon emission reduction cost, thereby obtaining the carbon-coherence ratio of the scientific and technological achievements. The policy matching degree refers to the degree of conformity between scientific and technological achievements and policies issued by the state and local governments, such as whether scientific and technological achievements meet the specific requirements of policies such as the "Pumped Storage Power Station Plan". The subsidy amount is the amount of policy subsidies that the scientific and technological achievements can apply for under relevant policies.

[0037] Regarding market-related indicators, industrialization cost is the predicted unit cost (yuan / kilowatt) when the technological achievement is actually applied; the investment payback period is the predicted time (in years) required for the technological achievement to generate returns equal to the investment cost, i.e., the time required to recover the entire investment; and market penetration rate represents the market share of the technological achievement. Specifically, the industrialization cost, investment payback period, and market penetration rate of technological achievements can be dynamically predicted based on market data.

[0038] In some feasible implementations, obtaining the explicit parameters and implicit indicators of the engineering construction requirements includes: The explicit requirements of the project construction needs are analyzed using natural language processing technology to obtain the explicit parameters of the project construction needs. The fuzzy expression of the engineering construction requirements is analyzed by a pre-set large model to obtain the semantic keywords of the engineering construction requirements; The semantic keywords are converted into implicit indicators based on a preset indicator mapping library.

[0039] In this embodiment, the multi-dimensional requirement profile includes explicit parameters representing explicit requirements of engineering construction and implicit indicators representing implicit requirements. For explicit parameters, natural language processing techniques (such as named entity recognition) are used to parse the requirement document and extract explicit parameters, such as an installed capacity of no less than 500MW and a construction period of 18 months. For implicit indicators, firstly, a large model is used to parse the fuzzy expressions in the requirement document and extract semantic keywords, such as "zero carbon" corresponding to "carbon emissions during construction." Further, a pre-defined implicit requirement-quantified indicator mapping library is invoked to convert semantic keywords into calculable indicators, obtaining implicit indicators. For example, an implicit requirement-quantified indicator mapping library is constructed based on group engineering standards and industry specifications. Then, according to the implicit requirement-quantified indicator mapping library, "rapid response" is quantified as "charge and discharge response time ≤ 500ms," and "corrosion resistance" is quantified as "material corrosion resistance life ≥ 15 years." Optionally, implicit indicators can be validated by rules through large models, and implicit indicators with mapping deviations can be adjusted to ensure the engineering practicality of implicit indicators. For example, "high stability" needs to be modified to "continuous operation without failure time ≥ 8760 hours" in combination with specific scenarios.

[0040] In some feasible implementations, the calculation based on the multi-dimensional achievement profile and the multi-dimensional demand profile to obtain the technological compatibility, policy impact, and market benefit between the candidate scientific and technological achievements and the engineering construction needs includes: The technical parameters are matched with the explicit parameters and the implicit indicators to obtain the parameter matching rate between the candidate scientific and technological achievements and the engineering construction requirements; The technology adaptability is calculated based on the parameter matching rate and the cross-domain reusability. The core elements of the policy information are extracted using the large model. These core elements include at least the policy level, applicable field, subsidy standard, and validity period of the policy information. The impact of the policy is calculated based on the policy level, applicable fields, subsidy standards, and validity period. The market profitability is calculated based on the industrialization cost, investment payback period, and market penetration rate.

[0041] In this embodiment, the specific calculation process for the technology adaptability is as follows: First, the technical parameters are matched with explicit parameters and implicit indicators respectively to determine the parameter matching rate between the candidate scientific and technological achievements and the engineering construction requirements. As an example, the extracted technical parameters (such as an installed capacity of 500MW and a construction period of 18 months) are compared with explicit parameters. If a preset threshold is met, the explicit requirement is determined to be successfully matched, such as an installed capacity ≥ 90% of the required capacity and a construction period ≤ 110% of the required construction period. Based on the successful matching of explicit requirements, the technical parameters are matched with implicit indicators. For example, if the technical parameter charging and discharging response time is 450ms, and it meets the implicit indicator "charging and discharging response time ≤ 500ms", then the score for this technical parameter is 100 points. The parameter matching rate is calculated based on the weighted average of the scores of each technical parameter, and the weights of explicit parameters and implicit indicators can be adaptively adjusted. Furthermore, the cross-domain reusability score of the scientific and technological achievement for the target engineering field is obtained from the multi-dimensional achievement profile, such as a score of 85 points; finally, the technical fit between the candidate scientific and technological achievement and the engineering construction needs is calculated based on the parameter matching rate and cross-domain reusability. For example, the technical fit = parameter matching rate × 70% + cross-domain reusability × 30%.

[0042] The specific calculation process for policy impact is as follows: First, policy information is captured in real time using web crawler technology, and the core elements of each policy are extracted using a large model. The core elements include policy type (e.g., national, provincial, municipal), applicable field (e.g., new energy), subsidy standard (e.g., 20% investment subsidy), and validity period. Next, a policy impact model is constructed, with the weights set as follows: 40% for national policies, 30% for provincial policies, 20% for municipal policies, and 10% for district policies. Finally, the core elements associated with the candidate scientific and technological achievements and their corresponding policies are input into the policy impact model to output the policy impact of the candidate scientific and technological achievements.

[0043] The specific calculation process of market profitability is as follows: the market profitability of candidate scientific and technological achievements is calculated based on industrialization cost, investment payback period and market penetration rate. As an example, market profitability = (1 / investment payback period × 40% + market penetration rate × 30% + (industry benchmark industrialization cost / predicted industrialization cost of scientific and technological achievements) × 30%).

[0044] In some feasible implementations, the step of determining the target scientific and technological achievement corresponding to the engineering construction needs from the candidate scientific and technological achievements based on the technology adaptability, policy impact, and market profitability includes: The matching score of the candidate scientific and technological achievements is obtained by weighting and integrating the technology adaptability, policy impact and market benefit. Based on the matching score, the target scientific and technological achievement corresponding to the engineering construction needs is determined from the candidate scientific and technological achievements.

[0045] In this embodiment, firstly, the technological adaptability, policy impact, and market profitability of candidate scientific and technological achievements are weighted and integrated to obtain a matching score for the candidate scientific and technological achievement. For example, the matching score = technological adaptability × 30% + policy impact × 30% + market profitability × 40%. Further, the candidate scientific and technological achievements are ranked according to their matching scores, and the requester can select one or more of the top-ranked candidate scientific and technological achievements as the target scientific and technological achievements corresponding to the engineering construction needs.

[0046] In some feasible implementations, the method further includes: The engineering construction requirements are analyzed using the aforementioned industry chain knowledge graph, and cross-domain results corresponding to the engineering construction requirements are recommended.

[0047] In this embodiment, a supply chain knowledge graph can be used to analyze engineering construction needs, matching technological achievements from other fields with these needs, thereby recommending such achievements to the construction project. For example, based on the supply chain knowledge graph, it can be discovered that engineering construction needs are technologically related to engineering construction needs in other fields, such as both involving "high-altitude construction." Therefore, technological achievements from other fields can be recommended to the demand side, such as recommending the high-altitude construction technology of the Three Gorges Dam to the photovoltaic power station construction needs in Tibet.

[0048] In some feasible implementations, the step of parsing the candidate technological achievements based on the industry chain knowledge graph to obtain the cross-domain reusability of the candidate technological achievements includes: The technical principles and application scenarios of the candidate scientific and technological achievements are extracted using the aforementioned industry chain knowledge graph. Traverse the industry chain knowledge graph to determine the target domain of the engineering construction needs and the corresponding technical requirement scenarios of the target domain; The similarity in principle and the overlap in scenario between the candidate scientific and technological achievements and the target field are calculated by using a pre-set large model based on the technical principles, application scenarios and technical demand scenarios. Obtain the reuse rate of the candidate scientific and technological achievements for engineering practice cases in the target field; The cross-domain reusability of the candidate scientific and technological achievements is calculated based on the similarity of the technical principles, application scenarios, and reuse rates of engineering practice cases.

[0049] In this embodiment of the application, the specific process for determining the cross-domain reusability of candidate scientific and technological achievements is as follows: the technical principles and application scenarios of the scientific and technological achievements are extracted based on the knowledge graph of the industrial chain; the corresponding industrial field, i.e., the target field, is determined based on the engineering construction needs; the knowledge graph is traversed to obtain the technical demand scenarios of the target field; the similarity between the technical principles of the scientific and technological achievements and the target field is calculated through a large model (e.g., the semantic matching degree between the technical principles and the technical demand scenarios is ≥80%, which is considered a high correlation), and the overlap of application scenarios is calculated (e.g., the number of overlapping core functional items between the technical principles and the technical demand scenarios is ≥2); the reuse rate of the candidate scientific and technological achievements in engineering practice cases of the target field is obtained based on historical case data (e.g., the success rate of the application of the scientific and technological achievements to the target field); and the cross-domain reusability of the candidate scientific and technological achievements in the target field is determined based on the similarity of technical principles, application scenarios, and reuse rate of engineering practice cases.
