智慧城市试点政策对节能减排影响机制分析

Mechanism Analysis of the the Impact of Smart City Pilot Policies on Energy Conservation and Emission Reduction

[研究目的]我国在经济快速发展的同时,从2012年开始,通过分批智慧城市试点政策积极推动节能减排和产业结构升级,这一举措对实现社会主义现代化具有重要意义和研究价值。[研究方法]以2009—2019年282个地级市的面板数据为研究对象,采用多期双重差分回归方法,研究智慧城市试点政策对节能减排的影响,并运用平行趋势检验、时间异质性检验和内生性检验(PSM-DID)方法进行稳健性检验,验证研究的正确性。[研究结论]研究发现,智慧城市试点政策显著降低了单位GDP能耗,且其政策效应随时间增强。为进一步推进智慧城市建设,一是由国家层面机关推行政策并提供方案指导;二是地方政府与高校等研究机构积极合作,促使政策长期化稳定推行;三是支持高新技术和绿色产业发展,充分发挥智慧城市在节能减排中的作用。

[Research purpose]In conjunction with China’s swift economic ascent,the initiation of smart city pilot policies in a phased manner from the year 2012 has been instrumental in propelling energy conservation and emission reduction,as well as the advancement of industrial structure optimization.This initiative holds profound significance and possesses substantial research merit in the context of achieving socialist modernization.[Research method]This paper leverages panel data from 282 prefecture-level cities over the decade from 2009 to 2019.It employs a multi-period difference-in-differences regression approach to scrutinize the impact of smart city pilot policies on energy conservation and emission reduction.To fortify the validity of the study,robustness checks are implemented through parallel trend analysis,temporal heterogeneity assessment,and propensity score matching(PSM)methods.[Research conclusion]The research uncovers that the smart city pilot policies have markdely diminished energy consumption per unit o f GDP,with an observable escalation of the policy’s efficacy over time.To bolster the development of smart cities,the following recommendations are proffered.First,the national authorities do the promulgation and strategic guidance of policies.Second,local governments and academic institutions take vigorous collaboration to ensure the enduring and stable implementation of policies.Third,it gives a endorsement of the high-tech and green industry sectors to harness the full potential of smart cities in the realm of energy conservation and emission reduction.
