ANALYSIS OF SPATIAL-TEMPORAL EVALUATION OF REGIONAL TECHNOLOGY RELATIVELY EFFICIENCY IN CHINA
用改进的DEA方法测度中国30个省份1990-2008年的技术相对效率，发现其存在空间自相关和集聚特征，且与经济发展呈负相关，技术扩散能力有限。
Introducing of TOPSIS ideas,this paper using the improved DEA method measures technology relatively efficiency of 30 provinces in China from 1990 to 2008.The exploratory spatial data analysis(ESDA) is utilized to investigate spatial-temporal differences characteristics and distribution patterns of technology relatively efficiency and matches spatial feature of technology relatively efficiency and regional economic differences.Results indicate that: technology relatively efficiency is significantly spatial autocorrelation,showing characteristics of spatial concentration.Technical efficiency shows reducing trend gradually,having the function of promoting regional economic convergence.Technology relative efficiency and economic development shows a negative correlation of binary space,so factor inputs are the dominant factor in economic growth.The diffusion capacity of technical efficiency and economic radiation is imited,so technical efficiency is not yet a source of coordinated development of regional economy,and economic development is not the only factor of technical efficiency.Improving technical efficiency through technology diffusion effect is the focus of attention.
