将同一城市开展创新型城市和低碳城市建设所形成的双试点政策看作一次准自然实验,使用渐进双重差分法实证分析双试点政策对城市经济绿色发展的影响效应。研究表明,双试点政策能够对城市经济绿色发展产生协同作用,相较于单试点,双试点能更有效地促进城市经济绿色发展。机制检验结果显示,双试点政策主要通过绿色技术创新和产业结构变迁两大途径来促进城市经济绿色发展。异质性分析结果显示,双试点政策对经济绿色发展的促进作用在不同地理位置、规模和资源禀赋的城市表现出一定的差异性。进一步的分析结果显示,双试点政策对经济绿色发展具有空间溢出效应,能够带动邻近城市经济绿色发展;双试点政策在提高城市经济绿色发展综合水平的同时,能够在不牺牲经济增长的前提下促进减污降碳和提升能源效率。研究结论为优化试点政策结构、促进中国经济绿色发展转型提供了参考和启示。
The present study examines the impact of dual pilot policies on the green development of the urban economy, focusing specifically on the integration of innovative cities and low-carbon cities within the same urban context. To assess this impact, the asymptotic Difference-in-Difference model is employed to conduct an empirical analysis. The findings reveal that the dual pilot policies have a synergistic effect, facilitating the promotion of green development in the urban economy when compared to single pilot policies. Mechanism tests indicate that these dual pilot policies primarily drive green development through two main channels: green technology innovation and industrial structural transformation. Heterogeneity analysis further demonstrates that the effectiveness of the dual pilot policies in promoting green development varies across cities with different geographical locations, sizes, and resource endowments. Moreover, the research findings indicate that these policies can generate spillover effects, positively influencing the green development of neighboring cities. Notably, the dual pilot policies not only enhance the overall level of green development in the urban economy but also effectively contribute to pollution reduction, carbon abatement, and energy efficiency improvement, all without compromising economic growth. Consequently, the study’s results offer valuable insights and inspiration for optimizing the pilot policy structure and facilitating the transformation of China’s green economic development.
