Research On The Evolution Of Village And Town Logistics Ecosystem Dominated By "Platform-module"

Under the vigorous promotion of China's urbanization development and the construction of agricultural modernization,the "urban-rural dual" structure is shifting to the "urban-town-rural" triple structure,making village and town as a link between urban and rural areas,connecting industry and agriculture,and undertaking the dual two-way logistics bridge status is more prominent than ever.Under the pressure conditions of industrial upgrading,high cost,space constraints and traffic congestion,cities are promoting the development of urban logistics to a high-end platform and moving the physical logistics industry outward.However,in the absence of active factor support and logistics infrastructure support,rural logistics began to seek to build a village and town logistics platform with more abundant resources and closer markets.Besides,the development of the Internet economy has promoted the separation of physical space and virtual space,making village and town logistics get rid of traditional restrictions such as geographical location,market distance,and resource endowment.It takes advantage of low-cost land,which promotes the "urban-town-rural" ternary logistics form and logistics space reconstruction,thus forming the logistics system of urban and rural integration.Under this realistic background,this thesis selects village and town logistics as a vital research object to having the essential practical significance.In order to reveal the changes in the role and status of village and town logistics in the development of the times,the thesis starts with the study of the internal evolution of village and town logistics systems,furthermore,constructs village and town logistics ecosystem structure in Chapter 3 through the comparative analysis,and analyzes the evolution direction,the evolution path,the evolution mechanism of the village and town logistics system gradually through sophisticated theory methods in Chapter 4 and 5such as the systematic theory,the population ecology theory,and the evolutionary game theory,and Chapter 6 verifies by system dynamics simulation.According to the research,the thesis has achieved the following three innovations:(1)Through various ways of research,this thesis constructs a "three elements,four ecological flows,and double circles" village and town logistics ecosystem architecture.The framework contains three main types of agent: the core elements of village and town logistics,the supporting elements of village and town logistics,and the environmental factors of village and town logistics;four types of ecological flows: material flow,capital flow,technology flow and personnel flow;"Chain-function" is the first layer and "platform-module " is the leading layer.Among the two layers,the platform is on the top layer;The module is dynamically combined into a flexible chain,and the function is integrated into the platform and the modular flexible link.At the same time,the architecture is also an ecological system composed of "ecological element-ecological chain-ecological network-ecological group-ecological circle-ecological system."(2)This thesis combines ecological theory and system theory research to reveal the ecological evolution mechanism,path and direction of village and town logistics.Among them,the ecological element changes in the three main types of agent are the basis of evolution.Technological dependence,institutional dependence,and relationship dependence are the path of equilibrium evolution.Ecological flow is the driving mechanism of promoting the evolution of village and town logistics.The changes in niche caused by symbiotic and competitive mechanisms are evolutionary transmission mechanism;"Coupling-synergy" is an evolutionary amplification mechanism;"Chainfunction" leading mode to "platform-module" leading is the evolution direction of village and town logistics ecosystem.(3)The research content of this thesis has drawn a vital management enlightenment."Two-way dual network-double-layer platform" is the evolutionary framework of the urban-rural integrated logistics ecosystem.Agricultural produce enters the city,industrial products go to the countryside,and the two-way logistics and the massive circulation brought by the regional division of labour together form the two major market networks,rural and urban.Rural logistics is looking for resource advantages and market advantages to build a logistics platform.On the one hand,urban logistics upgrades to a high-end and develops a virtual network platform dominated by informatization.On the other hand,it squeezes to the low end to shift the physical logistics platform outward through the alternative method of fast delivery and economic cost adjustment.As a result of the two forces,the leading virtual platform of urbanization and the physical logistics platform of villages and towns are separated,forming an urban-rural integrated ecological architecture of "two-way dual network-double-layer platform".The modern centralized delivery/distribution "connect the platform and network.Based on achieving innovative results,the thesis also forms the following research conclusions:(1)This thesis adopts the improved three-stage DEA-Malmquist index method to process the input and output data of village and town logistics service nodes from 2009 to 2013.Through the study of the efficiency of "chain-function",after 2012,due to the explosion of Internet technology,the electrical contractor bilateral market dominated by "platform-module" makes the operational efficiency of village and town logistics service subject from divergence to convergence.(2)This thesis uses evolutionary game theory combined with the income matrix and dynamic replication equations to analyze the cooperation mechanism between the operating entity of the village and town e-commerce platform,platform usage entity and the government.The technological innovation with the Internet as the core is an essential support for the development model of "platform-module".At the same time,the network platform also promotes the industrial upgrading and spatial reconstruction of urban and rural logistics.MATLAB is used to simulate and draw the same conclusion.(3)Based on non-equilibrium mechanics,this thesis constructs the internal update fractal mechanism of village and town logistics ecosystem.Through the quantitative analysis of the theoretical model,it has concluded that "ecological flow" has a fractal effect on the spatial and temporal structure of village and town logistics ecosystem.The change of spatial structure of village and town logistics is the basis of the evolution of village and town logistics ecosystem,and the spatial differentiation of the internal "ecological flow" is the essence of system evolution.(4)This thesis uses SOM neural network to simulate and predict the effect of "ecological flow" and finds that,under the condition of the stable external environment,the spatial self-organization of village and town logistics ecosystem grows slowly.After 2012,driven by the urbanization policy,the spatial environment of village and town logistics has changed drastically and entered a new dimension of spatial reconstruction and scale growth,which makes the entire evolution process a typical leap forward,however,the expansion of logistics scale still lags behind the expansion of the built-up area of villages and towns.(5)Based on the 2006-2026 historical data and development forecast of village and town logistics environment subsystem,and by predicting three interactive scenarios through system dynamics simulation,this thesis concludes that increasing education funding and logistics technology investment can promote the overall " coupling-synergy " state improvement of the environmental subsystem.However,from the perspective of effect,the policy has apparent effects on the economic and social subsystems and has a weak effect on resources and the environment.
