【摘要】 为了发挥以出口为代表的市场力量对城市规模的作用，需要厘清出口贸易对城市规模的影响效应。本文基于2003—2018年中国282个城市的经济地理和夜间灯光数据，构建纳入要素市场与产业集聚模式的出口贸易影响城市规模理论框架，探讨出口在城市规模动态变化中的作用机制。研究发现：出口贸易对城市规模的影响存在倒U型关系；在经济较为发达的东部、中部地区以及非资源型城市均存在这种倒U型关系，但在经济较不发达的西部、东北部地区和资源型城市不存在。此外，出口贸易主要通过影响要素市场和产业集聚影响城市规模。本文结论对新型城镇化战略的实施具有一定的参考价值。更多还原

【Abstract】 To give play to the role of market represented by export in city growth, we need to understand the influence of export trade on city size. Based on the economic geography and nighttime lighting data of 282 cities in China from 2003 to 2018, we construct a theoretical framework for the influence of export trade on city size that incorporates factor markets and industrial agglomeration patterns, and explore the impact mechanism of exports in the dynamic change of city size. It is found that there is an inverted U-shaped relationship between export trade and city size; this inverted U-shaped relationship exists in the more economically developed east-central region as well as in non-resource-based cities, but not in the less economically developed western and northeastern regions and resource-based cities. In addition, export trade affects city size mainly through influencing factor markets and industrial agglomeration. The findings of this paper provide some reference value for the strategic implementation of new urbanization.更多还原
