Research On The Evaluation And Structure Adjustment Of The Development Of Chinese Green Food Industry

As an important rising industry in the development of national economy, the development of green food industry plays an important role in the optimization of industry structure and the improvement of economy development quality to some extent.At present, Chinese green food industry has made tremendous achievement, but it still could not meet the development of national economy for the weakness of irrationality of the industrial structure, inefficiency and non-coordination and so on.The rapid development of green food industry has attracted much attention and corresponding research is being conducted.However, little literature is found to explore the inherent development law and the systematic evaluation of green food industry development.Therefore,it has an important theoretical and practical value to evaluate the development characteristics of green food industry and to put forward policy measures such as adjusting the industry structure,which makes up the deficiency in this research field.With the direction of Marx's economy growth theory and industry development theory, western economy growth theory, industry life cycle, industrial structure optimization, industrial dynamics and systematic science, this dissertation constructed a theoretical analytic framework of industrial economics system to study the development of green food industry with such methods as qualitative and quantitative analysis, positive and normative analysis and so on.Based on the definition of green food industry and the connotation of industry development, this paper analyzed the evolution process of green food industry and "structural constraints" which restricts its development, used development experiences of organic food industry in some developed countries for reference, and explored the influential factors and endogenous development mechanism.Furthermore, this dissertation evaluated the scale,structure, efficiency and their coordination using empirical analysis. The corresponding and operable policy suggestions were put forward to offer scientific policy-making reference and decision-making basis.Firstly, the dissertation studied the characteristics of the development of green food industry by analyzing the status quo and problems of green food industry development, and provided the thinking for the industry development by using foreign development experience of organic food industry in developed countries for reference. With the dynamic factors and the evolution mechanism of Chinese green food industry development being studied by analyzing influencing factors, the paper pointed out that policies plays an important role in the adjustment of industry structure and green food industry development.Secondly, the development stage of green food industry is examined in the paper based on the theory of industry life cycle, and then Logistic curve and Gompertz curve is used to empirically research the development process. The paper studied the key factors which affect the output, the science&technique progress contribution rates and the growth model of green food industry using C-D production function, which is helpful to providing theoretical support for the transition of industry development mode and the transition of the industry development stage. It shows that the output of green food industry has a remarkable characteristics of "extensive mode" and mainly depends on scale expansion.Thirdly, this paper analyzed the structure of green food products by grey correlation and determined products class that should be strengthened such as processed products and aquatic products, and indicated that the development of green food industry can be achieved by the adjustment and upgrading of industry and product structure.The space-time evolution of the development of green food industry is analyzed by information entropy,which indicates that there exists "disequilibrium" characteristics in the regional distribution structure.The paper evaluated the development efficiency of Chinese green food industry by DEA method, empirical analysis results shows that the overall development efficiency is relatively low, the change of the comprehensive efficiency is due to the change of the returns to scale.Therefore, it is necessary to increase the investment in advanced factors,to adjust industry structure and to change the industry development mode so as to realize the sustainable development of Chinese green food industry.Fourthly,This paper constructed an index appraisal system of green food industry development, and established a coordination appraisal model to measure the coordinated development status of green food industry in Heilongjiang province based on PCA and grey system theory.The results showed that the coordination degree of scale development subsystem and the structure-efficiency development subsystem is not so satisfying and showed a downtrend along with time. Further study indicates that it's feasible to transfer the mode of industry development and to improve the structure-efficiency subsystem to realize the coordinated and sustainable development of the green food industry. Finally, relevant macroscopic adjustment policy measures include several aspects as follows:innovation of development mode, industrial structure optimization, industrial organization optimization and of government function exertive to ensure the healthy development of Chinese green food industry.Some innovations in this paper are as follows:Firstly,the paper constructs a systematic theoretical framework to analyze and evaluate the development of Chinese green food industry from scale,structure,efficiency and coordination. Secondly,this paper attempts to seek the inherent development mechanism on the basis of influential factors analysis.Thirdly,some empirical analysis of scale,structure,efficiency and coordination are made to demonstrate the development status and characteristics of Chinese green food industry,which laid a solid foundation for the transformation of industrial development mode,taking structural optimization for the theme and improve the efficiency and coordination of the development of green food industry by the optimization of industrial structure.
