Research On The Evolution Of China's Agricultural Product Logistics System Under The Background Of New Urbanization

Agricultural products logistics links agriculture,rural areas and farmers at one end,connecting industries,cities and citizens at one end.It is the fundamental way to solve the contradiction between supply and demand of agricultural products.The new urbanization will change the allocation of labor,information technology and other productive factors in different regions,cause significant changes in the consumption pattern and industrial pattern,and change the manifestation of the contradiction between the production and consumption of agricultural products,and then has an important impact on the logistics of agricultural products in China.Therefore,it is of great significance to study the development and evolution of China's agricultural products logistics under the background of new urbanization.This article relies on the National Social Science Foundation's major project Research on Innovation and Development Strategy of Agricultural Products Logistics System under New Urbanization(Project No.15ZDA022),focusing on the basic proposition of"how the agricultural products logistics in China will evolve under the new urbanization background",based on logistics system theory,self-organization theory,logistics geography theory,with the help of interpretation structure model,nuclear density analysis,standard deviation ellipse analysis and system dynamics,etc.,used Vensim,ArcGIS,MATLAB and other analysis software,deeply studies the essential connotation and evolution law of the agricultural product logistics system,reveals the internal relationship between the new urbanization and the agricultural products logistics in China and the mechanism of the new urbanization on the agricultural product logistics.Drew the following main conclusions:First,the evolution of agricultural products logistics in China is a self-organizing process.Social spatial structure,mode of agricultural production and operation and logistics technology are three order parameters of agricultural products logistics system in China.By comparing and analyzing the different performance of China's agricultural product logistics system in five stages of development,nine state parameters representing the characteristics of the system were summarized.On this basis,the hierarchical structure among the state parameters was clarified by the Interpretative Structural Model(ISM),and the three order parameters,namely,the social spatial structure,the mode of agricultural production and operation and the logistics technology,were obtained.Second,social spatial structure,agricultural production and operation mode and logistics technology became super-order parameters alternately,which in turn dominated the evolution of China's agricultural products logistics system.The transformation of social space structure from rural unitary structure to urban-rural dual structure lead to the spatio-temporal contradiction between the production and consumption of agricultural products and the formation of real agricultural products logistics.The transform of the mode of agricultural production and management from smallholder mode to collective mode and then to family contract mode lead the agricultural product logistics in China had experienced primary free purchase and sale,unified purchase and marketing,and the diversified development based on multi segment dual mode.The breakthrough of logistics technology from point breakthrough to integrated innovation and application lead to the emergence and development of modern agricultural products logistics.Third,the new urbanization changes the social space structure from"city-village"dual structure to "city-town-village" three dimensional structure,which leads to the substitution of the super-order parameters of the agricultural product logistics system in China,and then leads the system to a new orderly structure evolution.The new urbanization,characterized by urban and rural co-ordination,will form a new regional form,that is small town,whose social stratum,space density and economic form are between cities and rural areas,and then causes social space structure to be changed from"city-village" to "city-town-village" and becomes the order parameter with the biggest fluctuation,and replaces the logistics technology as the new super-order parameter,leading the agricultural product logistics system to form a new order structure.Forth,under the effect of super-order parameter substitution,the new urbanization has a great impact on the elements,structure and function of China's agricultural products logistics system.Through the deduction of Thunen Kreise theory,it is concluded that the circulation nodes of agricultural products logistics will be separated from the comprehensive nodes of agricultural products logistics,and the comprehensive nodes of agricultural products logistics will gradually transfer to small towns.The new urbanization will change the linking relationship and the linking mode of factors,promote the rapid development of modern direct selling model represented by agricultural electronic commerce,promote the agricultural products logistics service providers to form a network organization based on cooperation agreements,and change the dominant position of business flow.In terms of system functions,the new urbanization will lead to a circular distribution of the seven basic functions.At the same time,it is endowed with the new functions of absorbing and transferring population,narrowing the gap between urban and rural areas,and ensuring the sustainable development of society.Fifth,empirical test in the context of new urbanization,small towns have become a good carrier for sustainable development of comprehensive nodes of agricultural products logistics.Taking Beijing as an example,this paper uses the methods of nuclear density analysis,standard deviation ellipse analysis and system dynamics,from the perspectives of historical evolution and future development,to verify that under the influence of the new urbanization,the comprehensive nodes of agricultural products logistics represented by the wholesale market are gradually moving to small towns under the influence of the new urbanization,showing a new feature of cross-administrative areas and cross-city grade diffusion.The innovation points of this article are as follows:(1)Identifying the social spatial structure,agricultural production and operation mode and logistics technology alternately became the super-order parameter leading the evolution of China's agricultural products logistics system.Starting with the self-organizing characteristics of agricultural product logistics evolution,by means of comparative induction and explanation structural model,this paper revealed that the social spatial structure,the mode of agricultural production and operation and the logistics technology alternately became the super-order leading the agricultural products logistics in China had gone through five development stages.We have realized the inherent law of the evolution of China's agricultural products logistics system from the intrinsic level of the system.(2)It revealed that the new urbanization promoted the change of social spatial structure from "city-village"dual structure to "city-town-village" three dimensional structure,thus triggered the substitution of super-order parameter of China's agricultural logistics system.Based on the essence of new urbanization and with the three order parameters of the system as the breakthrough point,this paper found out that the social spatial structure was the internal relationship between the new urbanization and the agricultural products logistics,that is,the change of social spatial structure promoted by the new urbanization would stimulate the social spatial structure to become a new super-order parameter of the agricultural product logistics system,thus triggered the system to realize the super-order parameter substitution,and forming a new round of system evolution.(3)This paper deduced and demonstrated that under the effect of the new urbanization leading to the super-order parameter substitution,small towns would become a good space carrier for comprehensive nodes of agricultural products logistics realizing the optimal allocation of resources.Under the guidance of the three-dimensional coordinated social spatial structure of,"city-town-village",under the influence of the new agricultural production and operation mode,and with the support of integrated logistics technology,the comprehensive nodes of agricultural products logistics represented by agricultural product logistics park would transfer to small towns with certain industrial base and location advantages in urban agglomerations to achieve sustainable development.
