高铁开通对中国资源型城市经济转型的影响

高铁作为现代社会的一种新型运输方式，是资源型城市经济转型的重要外部驱动力。基于此，以2004—2018年中国114个资源型城市的面板数据为基础，选择多期双重差分法，探讨高铁开通对中国资源型城市经济转型的影响，结果表明：总体上，高铁开通对资源型城市的产业结构转型和经济增长均具有显著的促进作用；高铁开通对资源型城市经济转型存在明显的地区异质性：高铁开通对沿海资源型城市产业结构优化具有显著的促进作用，对其经济增长影响却并不明显，而与之相比，内陆地区资源型城市产业结构优化受高铁影响并不明显，其经济增长受高铁影响比较显著；高铁开通对不同发展周期的资源型城市经济转型作用也存在异质性：高铁开通对成长再生型资源型城市产业结构优化的促进作用显著，而对成熟型、衰退型资源城市的产业结构优化作用并不明显，与之相比，高铁开通对成长再生型和成熟型资源型城市经济增长影响并不明显，而对衰退型资源型城市经济增长有显著的促进作用。

The influence of high-speed railway on the economic transformation of resource-based cities in China

As a new mode of transportation in modern society, high-speed railway is an important external driving force for the economic transformation of resource-based cities. Based on the panel data of 114 resource-based cities in China from 2004 to 2018, this paper analyzes the impact of the opening of high-speed rail on the economic transformation of resource-based cities in China by adopting the multi-period differential difference method. The results show that: In general, the opening of high-speed railway plays a significant role in promoting the industrial structure transformation and economic growth of resource-based cities. The opening of high-speed rail also has a heterogeneous effect on the economic transformation of resource-based cities in different development periods: The opening of high-speed railway has a significant promotion effect on the optimization of the industrial structure of coastal resource-based cities, but its impact on economic growth is insignificant. In contrast, the optimization of industrial structure of resource-based cities in inland areas is not significantly affected by the opening of high-speed railway, and its economic growth is significantly affected by high-speed railway. The opening of high-speed rail also has heterogeneous impacts on resource-based cities with different development periods: The opening of high-speed railway has a significant promoting effect on the optimization of industrial structure in the growing and regenerating resource-based cities, but its effect on industrial structure optimization of mature and declining resource cities is not obvious. By contrast, the opening of high-speed railway has no obvious influence on the economic growth of the growing and regenerating and mature resource-based cities, but has a significant promotion on the economic growth of the declining resource-based cities.
