全要素生产率视角下的中心城市经济增长方式转变——基于中国17个城市面板数据的实证研究

The Change of Economic Growth in Central City from the Perspective of TFP——Based on 17 Chinese Cities Panel Data

我国经济进入新常态以后，各中心城市都将面临经济增长方式转变问题。该文运用DEA的Malmquist生产率指数方法，测算了中国17个中心城市2000～2013年的全要素生产率，并采用松弛变量分析了全要素生产率的城际差异。研究发现：中心城市全要素生产率在13年间提升了2．3％，其主要原因是技术进步；中西部中心城市仅依靠城市固定投资不能实现GDP产出最优，同时对投资松弛变量的测算结果表明：国有经济投资已不能促进上海等东部城市全要素生产率的提升，要实现经济增长方式的转变必须进行技术创新和产业结构调整。

Under the new normal economy, Chinese central city meets economic growth mode problems. Based on the DEA-Malmquist productivity index, this papar estimates the total factor productivity change of 17 central cities in China from 2000 to 2013. Then we analyze the slack variables of these inputs and outputs of dif- ferent cities and different years. The research finds that TFP of Chinese city has been great progress, TFP of the 17 central cities in 13 years improved by 2.3% ;the main contribution comes from the technological progress; the excess prevalence of GDP output is serious in western urban centers and these centers cities still have gaps in terms of investment in fixed investment ; Shanghai and other eatern cities need to raise the proportion of pri- vate investment, what＇ s more they also should continue to optimize the industrial structure and rational alloca- tion of resources.
