| Yizhou District of Hechi City seized the historical opportunity of "moving Mulberry from East to West" project and the development of advantageous industries in Guangxi Zhuang Autonomous Region,combined with its geographical advantages to develop silkworm industry chain,and made remarkable achievements,but there are still a series of problems in the silkworm industry chain of Yizhou District.In order to further promote the development of mulberry industry in Yizhou district,this paper uses literature research method and investigation research method,on the basis of fully understanding the industrial chain and related theories,using the "four-dimensional" theory of industrial chain to analyze the development status of silkworm industry chain in Yizhou District,and puts forward reasonable suggestions on how to further optimize the local silkworm industry chain.First of all,combined with the previous research results,the construction of the industrial chain theory of the framework of analysis.The industrial chain is an organic combination of supply-demand chain,value chain,enterprise chain and space chain.The paper analyzes the concept connotation of supply-demand chain,value chain,enterprise chain and space chain,as well as the mechanism of "four dimensions" forming the industrial chain.Secondly,at present,there are few researches on the empirical analysis of the "four-dimensional" mechanism of the formation of the industrial chain.This paper tries to put forward the analysis method of the four dimensions of the industrial chain,and analyzes the development status of the industrial chain of silkworm silkworm in Yizhou District based on the four dimensions.The supply and demand chain dimension is mainly to judge the development level of the supply-demand chain of the industry by analyzing the number of supply and demand chain,the scale of the chain and the material flow and information flow through each chain.Based on this analysis,it is found that the supply-demand chain of mulberry silkworm industry chain in Yizhou district is "short" and "thin".The value chain dimension is to analyze and judge the status of acquiring added value of the industrial chain through the "smile curve" theory.It is found that the value chain of silkworm in Yizhou district has the problems that the added value comes from the low added value link and the overall added value is low.The analysis method of enterprise chain dimension is mainly aimed at the analysis of the operating subjects of each industrial chain link and the mechanism of interest connection between operating subjects.It is found that the silkworm enterprise chain in Yizhou district has the problems of weak operating subjects and loose interest connection.The spatial chain dimension is to analyze the spatial chain status of a regional industry through the level of industrial agglomeration and factor endowment,and find that the mulberry silkworm spatial chain in Yizhou district has such problems as unreasonable industrial structure and insufficient factor support.Finally,based on the experience and inspiration of Japanese silkworm industry chain and Jiangsu silkworm industry chain,this paper coordinated the four dimensions of the industrial chain,and put forward specific countermeasures and suggestions for optimizing the industrial chain of silkworm in Yizhou District of Hechi City: strengthen and consolidate the key links of silkworm industry chain,and solve the problem of "thin" silkworm industry chain;Selectively complete the missing industrial chain links to solve the problem of "short" industrial chain;Promoting the depth of silkworm by-product processing and building the industrial chain of circular ecological silkworm;Create silkworm industry chain tourism;Improve the multi-subject interest linkage mechanism,reduce market transaction costs;Provide support for production factors,etc. |
