Research On The Generating Mechanism Of The Core Enterprise In Supply Chain

With the advent of the economic globalization and the age of knowledge-based economy, the competition between supply chains shows some new characteristics, and the core enterprise in the supply chain has started appearing many new attributes in the environmental turbulence, and its identification markings are increasingly blurred. Nowadays, the researches of the current domestic and international scholars on the core businesses often lay particular stress on the influence of core enterprise, evaluation of capacity and performance, modeling technology, information sharing, risk aversion and other fields, while ignoring the researches on the recognition of core enterprise and the drifting mechanism. The theoretical investigation of core enterprise seriously lags behind the supply chain practice, which has become the key constraint factor on the development of supply chain management.This thesis preliminarily studies the generated movement mechanism of the core enterprise and drifting trajectory. On the basis of empirical analysis on the typical supply chain to redefine the core enterprises, first, the thesis thoroughly explains the generation motive of the core enterprise, quantitatively analyzing the core enterprise on the basis of transaction cost theory, and creates a dynamic model of transaction cost to explore in greater depth to the causes of the form of core enterprises; then applies the META chart theory to establish the dual weights, level weights and index weights, and establishes the dynamically identifying and selecting model for the core enterprises and node enterprises and gives application examples; subsequently, applies the self-organization theory to discuss the evolution of core business, and studies the role of core enterprises and the impelling force during the evolutionary process of supply chain in the life cycle of the supply chain; finally, discusses the drifting motive of core enterprise and dynamic drifting dimension under the unsteady state, revealing the drifting trail and development trends of the core enterprise in supply chain.The thesis, based on the latest research results of domestic and international research on the core enterprises in supply chain, tries a new exploration on the following issues. (1) Based on the empirical research on pork food, production and sale of electric apparatus, supply chain of coal and electricity production, the core enterprise in supply chain is redefined; (2) the operational practice of the core enterprises in supply chain challenges to the theory of traditional transaction cost, and this requires us make new explanation to transcend the cost economics. The static treatment costs is supplemented by dynamic treatment costs, in order to form a complete concept of treatment costs, and then use management efficiency to supplement treatment costs, forming a comprehensive characterization of characteristics of treatment structure. Quantitatively analyze all the relevant factors of the core enterprise generating, and get the critical elements of the core enterprise generating. (3) The graphics theory is applied to the dynamic selecting model of the core enterprise in supply chain, using the META chart to express the relationships between enterprises in the supply chain. The node enterprise is divided into different layers based on its function in the supply chain, establishing the level weights, index weights to constitute dual weight, changing the way of dividing the weights only according to the nature of index in the past. Break through the way of setting weights according to index, the dual weights of the level weights and index weights are adopted. This evaluating model, to a certain degree, considers the fact that various operating indexes of enterprises in different levels affected differently on the supply chain and its core enterprises, making the weights more scientific and reasonable to identify and select the core enterprise better.With the structure of the supply chain more virtual, networking and dynamic, supply chain management will be more flexible, agile and lean, and the general trend of the future evolution of the supply chain is the core enterprises from the middle part of the supply chain drift gradually to the position at both ends of the supply chain, forming the "dumbbell-shaped dual-core supply chain" in which the resources vendors and retailers are core enterprises.
