A STUDY ON THE SPATIAL CONVERGENCE ANALYSIS OF REGIONAL ST INPUT-OUTPUT EFFICIENCY IN CHINA BASED ON DEA-GIS

摘要

For the incompletely random problem: the spatial distribution of regional S&T input and output efficiency in China, a new evaluation method based on DEA-GIS is proposed. This method makes the index of S&T quantified and homogeneity, and it can also qualitatively diagnose the space layout differences and dynamic imbalance of the relative efficiency of regional S&T input and output. Firstly, the traditional DEA method is used to calculate the relative efficiency and analyze effectiveness of regional S&T input and output from 2009 to 2012. Then, the Moran's I index is used to analyze the global relevance of the regional S&T input and output efficiency. Finally, Moran scatter plot and LISA cluster map are used to analyze the local relevance of regional S&T input and output efficiency, and the spatial agglomeration and abnormality of the efficiency are discussed. The new evaluation method provides the basis for reasonable allocation of the investment in S&T resources.
