Research On The Evolution Between Enterprises In The Supply Chain

The supply chain is promoted by the international as a new model of organization in the last 20 years. In essence, it is a new business model, its core issue is how to coordinate the relations between enterprises in the supply chain, which aims to improve the supply chain system to an more orderly organization, give full play of its supply chain as a whole strengths, in order to achieve of the state of harmony.From the point of ecological view, the supply chain is like an ecosystem, enterprises which constitute the supply chain is a limited,rational and organic life, has a certain ability to learn and statistics. So, not all the enterprises realize that cooperation can achieve a win-win situation in the start. The formation of the relationship between enterprises in the supply chain is a dynamic process of gradual evolution. In each game, through their own experience, observate other participants' decision-making in similar environments and imitate, or observe the history of the game from the distribution of group in access to the information of decision-making, to choose "cooperation" or "competition "strategy, to achieve their business growth in the ongoing process of the game.The game between enterprises in the supply chain can be divided into two levels of vertical game and horizontal game, horizontal game can be compared to the same game as the evolution game carried out by a population to get resources, we can use the change of the ratio of market share and business profits in the overall industry profit to representative the earnings. And the proportion of the market share and the profits reflects the corporate resources just from two areas. The market share can reflect the general location and state of corporate in the same industry, the proportion of profits in the overall industry could be on behalf of the enterprises' competitiveness. Finally, we come to the conclusion that competition and cooperation is the evolution of and the degradation of the direction of evolution. In the absence of the role of external forces, the ultimate evolution of the enterprise population is the result of competition, this is the direction of degradation; Another result is that cooperation, in the course of the game, The cooperation strategy is approved by all the enterprises, but because of Cooperation Strategy Evolution is not a stable strategy, in order to maintain such a state, the enterprises need external control mechanisms to increase the cost destruction to avoid a short-sighted acts which of the state of cooperation.The vertical game is a game between the populations, this thesis use the logistic model Lotka—Volterra model to construct the number and size of the population growth to representative the benefits in their games. We draw the conclusion that cooperation is the right direction of the supply chain Evolution, all enterprises in the supply chain should work for the common direction.The thesis also analyzes the role and strategies of the core business and non-core business in the process of the game. The core business should give full play to its own influence and a leading role in the supply chain to lead to a variety of controlling mechanisms and good culture of supply chain; for small and medium enterprises and non-core businesses, the most important thing is the establishment of core competence, or form cooperation group.
