Abstract:

In this article, the Malmquist-Luenberger index based on directional distance function and ESDA method are used to study the characteristics of GTFP change stages, regional differences and spatial agglomeration patterns of 108 cities along the Yangtze River Economic Belt from 2003 to 2014. Then the article divides the main types by GIS spatial superposition method to identify the problems of different areas. The results suggest the following findings: 1) The GTFP promotion considering undesired outputs of the Yangtze River Economic Belt is more obvious. The technological progress reflected by the pollutant reduction effect contributes to the improvement of TFP. 2) GTFP changes show great regional differences and significantly spatial clustering characteristics, and the GTFP promotions of the lower, the middle, the upper reaches of the Yangtze River Economic Belt decrease sequentially. The hotspot region distributes “dumbbell-shape”, and shifts from the lower reaches to the upper reaches. 3) The Yangtze River Economic Belt is divided into six types as GTFP growth lagging type, GTFP growth lagging due to technical change type, GTFP growth lagging due to efficiency change type, technical change lagging type, efficiency change lagging Type and GTFP steady growth type. Finally, the article puts forward the main ways to realize the coordinated development of protection and development in the Yangtze River Economic Belt from the aspects of promoting regional coordinated development, clarifying the main function, strengthening the radiation function of urban agglomeration and speeding up the transformation of green development power.

Key words: the Yangtze River Economic Belt, undesired outputs, GTFP, Malmquist-Luenberger index, regional types
