Abstract
Port integration (PI) can eradicate homogeneity and disorderly competition, realize the green intensive development of port cities, and is a crucial step in enhancing port competitiveness. This paper builds an assessment framework for green development efficiency (GDE) that takes social welfare, environmental regulation, economic growth into account, and uses the Super-SBM model to calculate the GDE based on panel data from 113 Chinese port cities from 2003 to 2020. Furthermore, the influence of PI on the GDE of port cities and its transmission mechanism is assessed using the PSM-DID model. The results show that the GDE of port cities has a fluctuating upward trend, but the overall level is low, and the social development index (SDI) can effectively improve the efficiency level. PI can significantly improve the urban GDE, and various robust results show that the above conclusions are credible. Heterogeneity analysis reveals that PI contributes more to the GDE of inland port cities than it does to coastal port cities. The GDE of the small-medium sized cities can be greatly enhanced by PI, and the results are better when the "Government driven + market decided" pattern is used. PI encourages technology innovation, which can enhance the urban GDE. Finally, some policy recommendations are made to encourage the excellent development of Chinese port cities.
港口一体化(PI)可以消除同质化和无序竞争,实现港口城市的绿色集约发展,是提升港口竞争力的关键一步。本文构建了一个综合考虑社会福利、环境规制、经济增长等因素的绿色发展效率(GDE)评估框架,并基于 2003-2020 年中国 113 个港口城市的面板数据,利用超级-SBM 模型计算了港口城市的绿色发展效率。此外,还利用 PSM-DID 模型评估了 PI 对港口城市 GDE 的影响及其传导机制。结果表明,港口城市 GDE 呈波动上升趋势,但总体水平较低,而社会发展指数(SDI)能有效提高效率水平。PI 可以明显改善城市 GDE,各种稳健结果表明上述结论是可信的。异质性分析表明,与沿海港口城市相比,PI 对内陆港口城市 GDE 的贡献更大。中小城市的 GDE 可以通过 PI 得到大幅提升,而采用 "政府推动+市场决定 "模式的效果更好。郫县鼓励技术创新,可以提高城市 GDE。最后,提出了一些鼓励中国港口城市卓越发展的政策建议。
期刊介绍:
Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
