基于PMC指数模型的可再生能源技术创新政策量化评价研究

Research on Evaluation of Renewable Energy Technology Innovation Strategy Based on PMC Index Model

可再生能源技术创新是我国实现能源转型的重要途经,我国政府已出台一系列引导和支持可再生能源发展的政策,其实施将影响可再生能源的进一步开发利用及其技术创新。在此背景下,系统梳理和评估可再生能源技术创新政策对完善现有政策体系具有重要意义。以2005—2021年期间出台的190项可再生能源技术创新政策为样本,从政策发文主体和政策主题词两个视角出发,采用文本挖掘和内容分析方法对政策样本进行现状分析和语义网络分析,识别出核心发文部门和政策主题词;构建PMC指数模型对筛选出的政策文本进行量化评价,根据其PMC指数分析政策整体优劣状况,利用模型二级指标PMC值反映核心部门发布政策及核心主题词相关政策的各维度表现情况。研究结果表明:可再生能源技术创新政策注重多部门之间的协同,发文部门的政策颁布时间分布不均;不同主题相关政策在政策的类型、领域、功能、支持措施方面各有侧重,但仍有待完善。最后从促进政策联合发布、强化政策连贯性及时效性、提升政策领域及功能全面性、丰富可再生能源技术创新激励措施等方面提出了政策优化建议。

Renewable energy technology innovation is an important way to achieve energy transition in China.Chinese government has issued a series of policies to guide and support the renewable energy development,and their implementation will further affect the development,utilization and technological innovation of renewable energy.Based on this,the systematic review and evaluation of renewable energy technology innovation policies is of great significance to improve the existing policy system.Taking 190 pieces of renewable energy technology innovation policies issued between 2005 and 2021 as samples,this paper uses text mining and content analysis methods to analyze the current situation and semantic network of policies from the perspectives of policy issuing agency and policy topic words.We identify the core issuing departments and policy topic words;and further construct the PMC index model for quantitative evaluation of policy texts.According to PMC index,the overall merits and demerits of the policies were analyzed.We used the PMC value of the model's secondary index to reflect the performance of the policies issued by the core departments and the policies related to the core subject words in various dimensions.We find the renewable energy technology innovation policies focus the coordination among multi-departments,and the policy promulgation time of the issuing department is uneven.Policies related to different topics present diverse focuses in terms of policy types,fields,functions and supporting measures,which remains to be improved.Finally,this study puts forward suggestions from the aspects of promoting policy joint release,strengthening policy coherence and timeliness,improving policy areas and functional comprehensiveness,and enriching incentive measures for renewable energy technology innovation.
