The Industrial Economic Transformation Efficiency Evaluation And The Policy Instrument Advice Of Xiaoyi City

City is a carrier of regional economic and social development. It has different problems In the process of development. Optimizing the industrial structure and improving the efficiency of industrial economic transformation are not only beneficial to crack the problems existing in the process of urban development, but also help to enhance the overall strength and competitiveness of the city. There are many problems in Xiaoyi city, such as over-reliance on the second industry, economic and ecological imbalance and so on. Based on the theory of industry structure, sustainable development theory and the theory of policy instruments, I use the literature induction, qualitative analysis, quantitative analysis, empirical analysis and data envelopment analysis to evaluate the industrial economic transformation efficiency of Xiaoyi city. And finally provide the policy instrument advice to further improve the industry economy transformation efficiency.The concrete content includes: First of all, the paper from regional situation, primary industry, secondary industry, and the third industry to respectively summary the industry development present situation. Secondly, drawing lessons from the current existing industrial economic transformation efficiency evaluation index, and learning from experts and scholars,visiting Xiaoyi city, I determine the industrial economic transformation efficiency evaluation index from the aspects of inputs and outputs. I also use the DEA to evaluate the Xiaoyi city industrial economic transformation efficiency and analyze it. Finally, with the aid of policy instruments, I provide the policy advice for Xiaoyi city. Agriculture is in the great transformation efficiency area, but it is a basic industry. In order to ensure the direction of the transformation of the first industry, we should mainly use the compulsory instruments and assist to use the mixed instruments and voluntary instruments. The animal husbandry transformation efficiency is higher, so we should mainly use the mixed instruments and voluntary instruments. The forestry and the fishery are in the poor transformation efficiency area, but they are not the dominant industry, so I think we can mainly use the mixed instruments and voluntary instruments, supplying the compulsory instruments by necessary. The transformation efficiency of the mining industry, the manufacturing industry, the construction industry, the electricity industry and so on is on the back. As the important industries, their transformation efficiency is related to the whole region. Sowe should mainly use the compulsory instruments and assist to use the mixed instruments and voluntary instruments to ensure the high efficiency. The efficiency is distinctive in different areas of the third industry. As the important part of the transformation, it determines whether the industrial economic transformation will be successful in the Xiaoyi city. So we should mainly use the compulsory instruments and use the mixed instruments and voluntary instruments by necessary.
