城市紧凑度与全要素生产率研究——基于面板数据GMM方法

A Study on Urban Compactness and Total Factor Productivity—Based on the GMM Method of Panel Data

城市化发展,城市蔓延问题日渐突出,城市面积扩大的速度远高于城市人口增长的速度、城市功能布局不合理带来城市的拥堵等都导致严重的效率损失。西方国家提出紧凑城市的理念,建设功能紧凑、规模紧凑和结构紧凑的现代城市。通过对2006~2012年中国城市面板数据的研究发现,城市紧凑度的提升有利于提高城市的全要素生产率,对于东部、东北地区尤为明显。对于中西部地区而言,建设紧凑城市的同时,应着力于解决拥挤问题。

The problems of urbanization development and urban sprawl have become more and more prominent, the speed of urban area expansion is too much faster than the increase of urban population, and the irrational layout of urban functions which brings urban congestion all lead to serious efficiency loss. The idea of compact city was proposed in western countries, which aims to build modern cities with compact construction functions, scales, and structures. Through the study on the panel data of China＇ s cities from 2006 to 2015, the authors find out that the improvement of urban compactness can help to improve the total factor productivity of the city, especially for cities in the east and northeast areas. For cities in the central and western areas, attentions should be put on solving the problem of congestion while building compact cities.
