制度供给与中国地区绿色创新效率

绿色创新带来经济和环境的双重回报，提升绿色创新效率是实现资源-经济-环境协调发展的重要途径。利用绿色创新随机前沿模型和2011-2015年中国省际面板数据，对地区绿色创新效率进行评价和比较，并着重对不同类型的制度所造成的影响进行了实证研究。结果表明:（1）中国地区间绿色创新效率差异较大，整体上呈现出东、中、西部依次递减的特征；从变化趋势来看，全国大部分地区的绿色创新效率有所提高，地区差异逐步减小。（2）地区绿色创新效率与各类制度正相关；其中，知识产权、金融、环境和财政制度的影响显著，尤其是金融和财政制度的影响敏感，而基础法律制度的影响不显著。此外，控制变量、要素价格和市场结构对绿色创新效率也具有重要影响。

Supply of Institutions and China's Regional Green Innovation Efficiency

Green innovation brings about the double returns for economy and environment,improving green innovation efficiency is an important approach to realize the balanced development of resources,economy and environment. By building a green innovation efficiency stochastic frontier analysis model and making use of China''s provincial data from 2011 to 2015,this paper evaluates and compares the green innovation efficiencies of China''s 30 provinces,and empirically exams the effects of different types of institutions. The results show that:first,during 2011 to 2015,the green innovation efficiencies of all provinces are about 0.52 on average,revealing the characteristics of going down from eastern,middle to western regions on the whole; as for the patterns of change,most of the provinces experience improvements in the green innovation efficiency,and the regional differences are gradually narrowing down. Second,the green innovation efficiency is positively correlated to all types of institutions; among the institutions,the impacts of the intellectual property institution,financial institution,environmental institution and fiscal institution are significant while the impact of the basic law institution is not significant. Besides,input prices and market structure also show important impacts.
