低碳试点政策与城市绿色技术创新——基于中国267城市数据的实证分析

Low-Carbon Pilot Policies and Urban Green Technology Innovation—An Empirical Analysis Based on Data from 267 Cities in China

摘要: 碳试点政策是我国为城市低碳转型推出的重要政策，城市绿色技术创新作为城市低碳转型的重要推力与低碳试点政策紧密相关。本文基于我国267个城市2005年至2021年数据为研究对象，通过实证分析探讨二者关系。研究表明，低碳试点政策能促进城市绿色技术创新发展，并且可以通过政府科技投入和人力资本水平两条路径来影响城市绿色技术创新，还证明了低碳试点政策对城市绿色技术创新的促进效应存在区域异质性。研究不仅为低碳试点政策促进城市绿色技术创新发展提供证据，还为后续政策实行提供建议。

Abstract: The low-carbon pilot policy is an important policy for urban low-carbon transformation launched by our country. Urban green technology innovation, as an important driving force for urban low-carbon transformation, is closely related to the low-carbon pilot policy. Based on the data of 267 cities in China from 2005 to 2021, this paper conducts an empirical analysis to explore the relationship between the two. The study shows that the low-carbon pilot policy can promote urban green technology innovation, and it can exert its influence on urban green technology innovation through two channels: government R&D investment and human capital level. The study also proves that the promotion effect of the low-carbon pilot policy on urban green technology innovation exists regional heterogeneity. The study not only provides evidence for the promotion of urban green technology innovation by low-carbon pilot policy, but also provides suggestions for subsequent policy implementation.
