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。
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.
