Identifying the relationship between carbon neutrality initiatives and its economic impact is crucial in evaluating the cost of low-carbon transition for policy makers. In this paper, a theoretical model is built to discuss the effects of the low-carbon pilot policy in China on urban economic resilience and an empirical test is conducted to examine the relationship using the Heckman two stage model and a panel data of 277 cities from 2004 to 2020. The results show that low-carbon pilot policy significantly enhanced urban economic resilience and the stimulating effect is mainly achieved by motivating technology innovations. In addition, further analysis indicates that low-carbon pilot policy has a more pronounced effect on improving urban economic resilience of cities in the central and western regions than eastern regions. The effect is also more prominent in non-first-tier cities than first-tier cities. The results are robust to placebo test, the Propensity Score Matching Difference-in-Difference test and the test for alternative measure of urban economic resilience. The findings show that the low-carbon pilot policy is consistent with the goal of improving urban economic resilience and technology innovation is the essential pillar of sustainable development.
确定碳中和倡议与其经济影响之间的关系对于政策制定者评估低碳转型的成本至关重要。本文构建了一个理论模型,讨论了中国低碳试点政策对城市经济弹性的影响,并利用 Heckman 两阶段模型和 2004 年至 2020 年的 277 个城市的面板数据进行了实证检验。结果表明,低碳试点政策显著增强了城市经济弹性,其刺激效应主要通过激励技术创新来实现。此外,进一步的分析表明,低碳试点政策对提高中西部地区城市的城市经济弹性的效果比东部地区更为显著。对于非一线城市而言,其效果比一线城市更为显著。安慰剂检验、倾向得分匹配差分检验和替代城市经济弹性衡量指标的检验均证实了结果的稳健性。研究结果表明,低碳试点政策符合提高城市经济弹性和技术创新的目标,技术创新是可持续发展的重要支柱。
