THE EVALUATION OF NATIONAL FOOD SECURITY INDUSTRY BELT CONSTRUCTION FOUNDATION BASED ON THE WHOLE INDUSTRY CHAIN
The purpose of this research is to evaluate the construction foundation of national food security industrial belt,and get the comparative advantages and shortcomings of different regions,so as to provide the basis and support for the regional development path.From the perspective of the whole industrial chain,the evaluation index system was constructed.And based on the entropy weight method,the global Moran index and the coupling coordination degree model,the development level,spatial correlation and coordination degree of the industrial chain of the national food security industrial belt in Northeast plain,Huang-Huai-Hai plain and the middle and lower reaches of the Yangtze River in 2020 were measured.The results were showed as follows.(1)Due to its outstanding comparative advantages in production,the Northeast Plain scored the highest,while the Huang-Huai-hai Plain had a significant comparative advantage in processing,and the middle and lower reaches of the Yangtze River Plain scored the lowest.(2)The geographical agglomeration characteristics of grain production and processing were significant.The regions with high scores were concentrated,but the agglomeration of circulation and service support were not significant.(3)The regional score ranking of coupling coordination degree was consistent with the development level,the Northeast plain was the highest,and its processing lagged behind other links,the Huang-Huai-hai Plain was in the middle,and the construction of the circulation was relatively lagging behind,and the middle and lower reaches of the Yangtze River plain was the lowest.Based on the results,in accordance with the principle of"strengthening advantages,improving weakness,highlighting key points and developing differently",it is concluded that the Northeast Plain,Huang-Huai-hai Plain and the middle and lower reaches of the Yangtze River Plain should adopt the differentiated development paths of green and high-quality production leading,circulation and processing integration and industry and trade driving respectively.
