摘要:

“一带一路”倡议为中国经济高质量发展提供了重要机遇,是新时代背景下实现绿色转型的重要推力。本文以“一带一路”倡议实施这一准自然实验为切入点,以城市绿色全要素生产率衡量绿色转型水平,运用双重差分法考察“一带一路”倡议实施对2004—2017年中国沿线城市绿色转型的影响及作用机制。研究发现:①“一带一路”倡议的实施显著推动了沿线城市的绿色转型,但存在城市类型和地理区位异质性,“一带一路”倡议对沿线城市绿色转型的推动作用主要存在于中心城市、非资源型城市、特大城市、中部地区城市和(0,200]地理圈层内城市。②在“一带一路”倡议实施过程中,科技创新效应尚未显著促进沿线城市绿色转型,但结构优化效应和资源整合效应发挥了积极作用。③结构优化效应和资源整合效应的发挥均存在门槛现象,当城市第三产业比重、大学生人口数量和外商直接投资额超过临界值时,结构优化效应和资源整合效应才能发挥推动城市绿色转型的正向作用。根据以上结论,在“一带一路”倡议建设过程中,建议政府继续完善相关配套政策,推动沿线城市进一步融入“一带一路”倡议;加强技术创新,激发科技创新效应对城市绿色转型的驱动作用;提高城市综合竞争力,实现对政策红利的高效利用。

Abstract:

The Belt and Road initiative provides an important opportunity for China to achieve high-quality development and it is an important driving force to achieve green transformation under the background of the new economic normal. This study took the Belt and Road initiative as a quasi-natural experiment, and used the difference-in-differences (DID) analysisto examine the impact of the Belt and Road initiative on the green transformation of Chinese cities along the route in 2004-2017 and the mechanism of impact. The study found that the implementation of the Belt and Road initiative significantly promoted the level of urban green transformation and development characterized by green total factor productivity, and there were heterogeneities in the level of urban green transformation between different city types and geographic locations. The initiative significantly promoted the green transformation in central cities, non-resource-based cities, megacities, cities located in middle area, and cities less than 200 km away from the central cities. Further analysis revealed that structural driving force and factor driving force played positive roles in the implementation of the Belt and Road initiative, but the effect of innovation driving force was insufficient. There is a threshold characteristic in the exertion of structural driving force and factor driving force, that is, they can promote urban green transformation when the proportion of urban tertiary industry, the number of college students and the amount of foreign direct investment exceed the critical value. Based on aforementioned findings, the government should continue to establish relevant supporting policies and promote the cities along the route to further integrate into the initiative; Cities should strengthen technological innovation, so as to stimulate the positive effect of innovation driving force on urban green transformation; The government should constantly improve urban comprehensive competitiveness, thus realizing the efficient utilization of policy dividends of Belt and Road initiative.
