城市建设用地扩张与经济增长效率关系的动态分析

A Dynamic Analysis of the Relationship between Urban Construction Land Expansion and Economic Growth Efficiency

中国经济发展的土地代价过高表明,需要考察经济增长效率对城市建设用地扩张影响的跨期响应,动态地评估城市建设用地扩张的绩效。基于城市建设用地与经济增长效率的互动机制,采用面板VAR模型,动态地评估了中国省际层面城市建设用地扩张与经济增长效率的互动影响。结果表明:短期内,城市建设用地扩张会抑制经济增长效率,但长期影响不显著。经济增长效率对城市建设用地扩张的影响不显著。从长期来看,经济增长效率的改善取决于自身的完善,城市建设用地扩张对其并无显著影响。应重视城市土地的节约集约使用,并增加经济增长效率在官员考核指标中的比重。

The high land costs of China＇s economic development showed that it was necessary to investigate the cross- phase response of impact of economic growth efficiency on urban construction land expansion. We should assess the performance of urban construction land expansion dynamically. Based on the interaction mechanism between urban construction land expansion and economic growth efficiency,this paper assessed the interactive effects of Chinese provincial level urban construction land expansion and economic growth efficiency under quality perspective dynamically through PVAR model.The results show that in the short term,the urban construction land expansion will inhibit the economic growth efficiency,but no significant impact in the long run. Economic growth efficiency doesn＇t have a significant impact on the urban construction land expansion. In the long run, improving the efficiency of economic growth depends on its own improvement,and effects on which from urban construction land expansion isn＇t significant. We should pay attention to economical and intensive use of urban land,increasing the efficiency of economic growth in the proportion of official assessment indicators.
