优化区域经济和国土开发空间结构有助于为产业的转型和经济结构的升级提供新的拉力并开拓更广阔的空间。本文利用主成分分析法对经济和国土开发的综合指数进行了测算,并分析了不均衡程度以及空间分布特征。分析结果表明我国经济发展差距逐渐减小,但是板块的分异明显,板块内和省内的不均衡程度在部分年份有所扩大。区域经济和国土开发在东部沿海和中部发生聚集,且聚集程度不断提高,其中中部地区的发展尤为迅速。在此基础上,本文从国家、板块和省区层面分别提出了政策建议。
Optimizing the regional economy and the spatial structure of land development will help to provide new rallying force and broader space for industrial restructuring and upgrading of economic structure. In this paper, we use the principal component analysis to measure the comprehensive index of economy and land development, and analyze the unbalance degree and the spatial distribution characteristics. The analysis shows that the gap between economic development in our country gradually decreases, but the division of plates is obvious. The degree of imbalance in the plate and province has been widened in some years. The regional economy and land development have gathered in the eastern coast and the central part of the country, and the level of gathering has been continuously increasing. Among them, the development in the central region has been particularly rapid. On this basis, the paper puts forward policy suggestions respectively from the aspects of country, plate and province.
