交通基础设施如何挖掘我国城市市场潜力——基于生产要素流动的视角

How does Transportation Infrastructure Excavate Chinese Urban Market Potential——From the Perspective of Production Factor Flow

本文使用了2003—2019年的城市面板数据,对交通基础设施对城市市场潜力的影响效应及机制进行了研究。研究结果表明:(1)交通基础设施的发展水平提升会促进城市市场潜力的提升,并存在市场潜力的溢出效应;(2)交通基础设施的发展水平提升会提升城市间可贸易品需求水平,提高城市市场潜在需求水平。交通基础设施的发展水平提升还会提升城市的有效劳动供给水平,挖掘城市市场潜力;(3)交通基础设施对城市市场潜力的最优影响范围约为100至150公里,该影响存在“梯度下降”现象。本文为进一步推动城市间互助联合、协同发展,提升城市潜力水平提供了现实依据。

This paper utilizes panel data from cities spanning the years 2003 to 2019 to investigate the effects and mechanisms of transportation infrastructure on urban market potential.The research findings reveal the following:(1)The improvement of transportation infrastructure enhances urban market potential and exhibits spillover effects on market potential.(2)The development of transportation infrastructure increases intercity demand for tradable goods and contributes to the growth of potential market demand for cities.Furthermore,it boosts the availability of skilled labor in cities,thereby unleashing their market potential.(3)The optimal range of the impact of transportation infrastructure on urban market potential is approximately 100 to 150 kilometers,demonstrating a“gradient descent”phenomenon.This study provides empirical evidence that can support the promotion of mutual cooperation and coordinated development among cities,aiming to enhance their potential.
