Research on the total factor productivity and decomposition of chinese coastal marine economy: Based on dea-malmquist index

Based on DEA-Malmquist index method, this paper analyzes the total factor productivity of 11 Chinese coastal cities' marine economy during the period of "11th five-year plan" and it comparatively analyzes the regional differences of economic efficiency in these areas. The results show the overall level of marine economy development efficiency of China's coastal cities is not high. According to the TFP decomposition, most regions have got reasonable urban resource allocation. Technology progress is the major force for developing marine economy. In regions which have got unreasonable resource allocation, with the decomposition of efficiency changing value, it shows that pure technical efficiency is the main reason of causing the change of low efficiency. What's more, scale efficiency develops either too fast or too slow. When government regulates and controls the development of marine economy, large hysteresis exists in policy guidance.
