A Study on Change and Difference of Provincial Fishery Efficiency in China

This paper uses Chinese provincial panel data, Data Envelopment Analysis (DEA) method, Malmquist index calculation method and Theil index decomposition method to study the efficiency of Chinese fishery and the structure of provincial fishery efficiency differences.The results show that in a large number of Chinese provinces, fisheries are in an inefficient state.In most provinces, fisheries have achieved efficiency gains, which is conducive to the improvement of fishery total factor productivity.The intra-regional differences within eastern, central, western and northeastern China are the major cause of the total provincial efficiency difference in fisheries, while the inter-regional difference is the minor cause.Based on the empirical results, this paper further discusses the relevant political implications.
