城市蔓延与城市全要素生产率

Study on Urban Sprawl and Urban TFP

基于我国长江经济带104个城市2001-2013年市级面板数据,实证研究了城市蔓延的影响因素及其对全要素生产率的影响,结果表明:工业、服务业发展集聚了大量就业人口是抑制城市蔓延的重要因素,而城市人口增长过快是加速城市蔓延的关键因素,合理控制城市人口规模,加快工业、服务业的发展是抑制城市蔓延的有效途径;城市蔓延对全要素生产率的影响显著为负,表明城市蔓延扩大了市场范围但降低了城市密度,抑制了全要素生产率的增长,也意味着长江经济带经济发展处于集聚阶段。

This paper empirically researches urban sprawl factors and the influence of urban sprawl on TFP based on 104 cities of China＇s Yangtze Economic Belt from 2001 to 2013 municipal panel data, and the results show that： Firstly, the rapid development of industry and services industry gathered a large number of the employed population , which is an important factor inhibiting urban sprawl, and urban population growth is a key factor to accelerate urban sprawl, therefore, reasonable control of the urban population size and speeding up industrial and service development industry are effective ways to inhibit urban sprawl; Secondly, urban sprawl on TFP is significantly negative, which indicates that urban sprawl expanded the market range but reduce urban density, that＇ s the reason of inhibiting the growth of total factor productivity, which also means that the economic development in the Yangtze River are on the gathering stage.
