新增工业用地效率的区域差异性研究

Study on Regional Differences in New Industrial Land Effi ciency

采用泰尔熵和MLD指数对我国总体及四大经济区新增工业用地效率的区域差异性进行了测度和分解,并对31个省份新增工业用地利用效率的变化规律进行了探寻。结果表明:从静态角度看,总体、经济区间及其内部的差距都呈缩小趋势。从动态角度看,经济区间的差距变动先缩小了总体差距后又扩大了总体差距,而经济区内部的差距一直缩小了总体差距。从省际角度看,各省新增工业用地利用效率呈梯度转移态势。

This paper estimates and explains the regional differences in the new industrial land efifciency of China as a whole and four major economic zones by theil entropy coefifcient and MLD index;and it also makes an exploration in the changing rule of the new industrial land use efifciency of 31 provinces. The results show that, from static point of view, the whole country, the differences between economic zones and their internal differences become shorten. From dynamic point of view, for the change of the gap between economic zones, the whole disparities are narrowed and then expanded;while the intra-EMR disparities have narrowed the gap as a whole. From the point of view on a provincial, the provincial new industrial land use efifciency has showed the gradient transfer.
