Analysis Of Competition And Cooperation Game Relation Among Medium And Small-size Enterprises In Cluster

In recent years, the phenomenon of cluster attracts public attention, local governments give lots of support to cluster, the scientists make deep study on cluster. Zhejiang and Guangdong provinces' economy developed quickly in recent years, most of which attributes to that the government's plan on cluster and cluster's development. Clusters have immeasurable effect on promoting the local economy to develop.But no matter what study such as to classify the cluster, to research the cluster's forming mechanism or to do some research on the competition advantage of clusters all view cluster as whole. This paper studies part of clusters, and gives some instruction to the enterprises in cluster through doing some research on the relationship of competition and cooperation of enterprises in clusters. For clusters have many kinds of classification, in this paper I pay more attention to medium-sized and small-sized clusters. These kinds of clusters are made up of medium and small-sized enterprises, the enterprises are in peer position, not like clusters made of big enterprises and medium-sized and small-sized enterprises, the big enterprises are in lead position.Enterprises in clusters are in dynamic change between competition and cooperation, then when to compete and when to cooperate? How do enterprises grasp the chance of competition and cooperation? Of course it is decided on profit. If by cooperation, the enterprise can make better profit, they will cooperate. So is competition. But enterprise's profit can only be measurable afterwards, how does enterprise decide to compete or cooperate with others?We here resume there are only two enterprises in cluster, they don't know each other's cost, they decide to compete or to cooperate only judging by price. One enterprise send price signal, if the price is high, the other enterprise then think its cost is high and competition will make more profit, then will compete with it. If the price is low, the other enterprise then think its cost is low and cooperation will make more profit, and then will cooperate with it. This is game analysis.In third part of this paper, author first summarizes the trait of competition and cooperation between medium-sized and small-sized enterprises. Author judges that medium-sized and small-sized enterprises in cluster prefer to cooperation than medium-sized and small-sized enterprises dispersed, and give some simple introduce to the form of competition and cooperation between medium-sized and small-sized enterprises in clusters. In the forth part of this paper, author proves that there is probability of cooperation between enterprises in clusters by using math formula then analyses the complete-information static competing and cooperating between enterprises game and makes a conclusion that low-cost enterprises easily develop relationship of competition and high-cost enterprises easily develop a relationship of cooperation. This paper also analyzes incomplete-information dynamic game, and makes a conclusion that when the price that enterprises make is lower than a certain level, the price can send the real cost information. In the fifth part of this paper, author explains enterprise in cluster has its special existing structure, there is intense competing relationship, and there is also cooperating relationship. If enterprises in cluster want to beat the game, it need improve enterprise's core competence, take full advantage of cooperation and innovation, make use of fit financing environment and utilize human-resource dominance. In the end, this paper gives some advice on government policy.
