摘要
基于2003—2016年中国213个地级市面板数据,应用双重差分法探讨了低碳试点政策的技术创新效应。研究发现:(1)总体看,低碳试点政策提升了城市技术创新,且在考虑环保约谈、创新城市以及智慧城市等其他政策后,虽然低碳试点政策对创新的作用有所减弱,但其对创新的正向影响依然十分显著。(2)机制分析发现,上述作用是通过增加科技人才数量、政策性研发资金投入以及产业结构升级实现的。(3)城市规模、发展类型以及空间区位不同,使得低碳试点政策的实施效果存在异质性。受生态脆弱、产业结构单一、创新基础薄弱以及区位劣势等因素的影响,资源型城市、大城市以及西部城市,低碳试点政策会阻碍其技术创新。
Based on the panel data of 213 prefecture-level cities in China from 2003 to 2016,the double-difference method was used to explore the technological innovation effect of the low-carbon pilot policy.The study found that(1)overall,the low-carbon pilot policy has improved urban technological innovation.Although the role of low-carbon pilot policies on innovation has weakened with the implematation of policies such as environmental talks,innovative cities,and smart cities,its positive impact on innovation is still significant.(2)The mechanism analysis found that the above effects were achieved by increasing the number of scientific and technological talents,policy research and development capital investment,and industrial structure upgrading.(3)Difference in the scale of the city,the type of development,and the location of the space may result in heterogeneous effect of the policy.Influenced by ecological fragility,single industrial structure,weak innovation base and location disadvantage,low-carbon pilot policies will hinder technological innovation in resource-based cities,large cities and western cities.
