企业异质性视角下我国绿色技术创新政策评估研究

绿色技术创新是解决经济与环境协调发展的重要途径。本项目在我国专利及其引证大数据分析的基础上，从专利的技术价值、市场价值和法律价值等维度出发，构建能反映企业绿色技术创新质量的指数，并利用网络分析方法研究绿色专利引证网络的演化特征；研究绿色专利及其引证数据与工业企业数据库、上市公司相关数据库的合并方法，建立我国企业绿色技术创新数据库；在考虑高管团队特征（如职业背景、社会资本、薪酬政策等）、企业融资结构、企业性质等异质性基础上，科学评估我国财政（如研发补贴、绿色补贴）、税收（所得税减免、研发费用税前抵扣）、金融（绿色信贷、绿色债券）、环保（排污权交易制度、排污费制度）、知识产权保护等一系列政策对企业绿色技术创新的影响机制；最后，模拟和评估相关政策及不同政策组合对我国企业绿色技术创新综合影响，研究我国绿色技术创新相关政策的有效性，为进一步完善我国企业绿色技术创新政策体系提供决策支持。

Based on the analysis of big data of patents and their citation, this project constructs an index that can reflect the quality of green technology innovation of enterprises from the perspectives of technical value, market value and legal value of patents, and studies the evolution characteristics of green patent citation network by using network analysis method; discusses the combination method of green patent and its citation data with industrial enterprise database and relevant database of listed companies, and establishes the database of green technology innovation of Chinese enterprises. After considering the characteristics of senior management team (such as professional background, social capital, salary policy, etc.), corporate financing structure, enterprise nature and other heterogeneity, this project discusses the effect of a series of policies related to the green technology innovation of Chinese enterprises, for example, R & D subsidies, green subsidies, income tax relief, Pre tax deduction of R & D expenses, green credit, green bonds, emission trading system, intellectual property and so on. Finally, this project simulates and evaluates the impact of policy changes on green technology innovation of Chinese enterprises, discusses the effectiveness of green technology innovation policy and provide decision support for further improving the policy support system of green technology innovation in China.
