摘要/Abstract

摘要： 创新驱动发展背景下，提高碳排放效率是实现绿色化、低碳化发展的关键环节。基于创新型城市试点建设的准自然实验，构建企业异质性分析框架，从理论与实证分析试点政策对城市碳排放效率的影响、传导机制与时空异质性，利用2006~2020年282个地级市的面板数据进行验证。研究表明：创新型城市试点政策会显著促进城市碳排放效率的提升；在影响机制方面，创新型城市试点政策会通过绿色技术创新与产业结构优化的渠道，提升城市碳排放效率；创新试点政策对碳排放效率的提升作用在不同区域、不同产业基础、不同规模的城市存在差异化影响；空间视域下，创新试点政策对碳排放效率的促进作用存在空间溢出效应，会显著带动150千米至250千米内城市碳排放效率的提升。

Abstract: In the context of innovation-driven development, improving carbon emission efficiency is a key link to achieve green and low-carbon development. Based on the quasi-natural experiment of pilot construction of innovation-oriented cities, an analysis framework of enterprise heterogeneity was constructed to analyze the impact of pilot policies on urban carbon emission efficiency, transmission mechanism and spatial-temporal heterogeneity from theoretical and empirical perspectives. Panel data of 282 prefecture-level cities from 2006 to 2020 were used for verification. The results show that:Pilot policies of innovation-oriented cities can significantly promote the improvement of urban carbon emission efficiency; In terms of influencing mechanism, pilot policies of innovation-oriented cities will improve urban carbon emission efficiency through green technology innovation and industrial structure optimization; The effect of innovation pilot policies on the improvement of carbon emission efficiency is differentiated in different regions, different industrial bases and cities of different sizes; From the spatial perspective, the promotion effect of innovation pilot policies on carbon emission efficiency has a spatial spillover effect, which will significantly drive the improvement of carbon emission efficiency of cities within 150 km to 250 km.

Key words: innovative city pilot, carbon emission efficiency, multiphase differential model, space decay law
