合作与经济增长

Cooperation and Economic Growth

近年来,虽然出现了大量对人类的合作行为进行研究的文献,但是这些研究都集中在微观层面。本文所关注的问题是:既然合作可以促进效率、提高经济主体的效用,那么社会上众多的合作行为总的效果是什么呢?加总的合作行为对经济增长能够产生多大的贡献?本文用规范的经济学研究方法将合作因素引入经济增长理论。在一个具有典型特征的社会群体合作演化的基础上,总结出群体合作程度变化的三个特征,然后进行线性近似得出群体合作程度的动态变化方程,并结合经典的经济增长模型,构造了一个包含合作因素的经济增长模型,刻画出合作与其他要素一起与经济增长之间互相促进、动态演变的过程。

In recent years, there have been a large number of literatures about human cooperation action. All of these studies, however, arc concentrated in the micro level. Since cooperation can promote efficiency and improve the utility of economic entities, what we concern is that what＇ s the accumulated effect of the entire community＇ s cooperation, and that to what extent the contributions are made by the overall cooperation actions to economic growth？ Therefore, this paper puts the factor of cooperation into the economic growth theory using the standard economic methods. On the basis of the evolution of cooperation in a typical society, we put forward a dynamics equation of the degree of cooperation. Then, we incorporate the dynamic equation into the classical model to build up an economic growth model containing cooperation, which depicts the dynamic evolution process of cooperation and the economic growth.
