摘　　要：在完全信息、生产者-消费者同质和生产函数收益递增的假设下,杨小凯通过一个分工理论模型内生出分工和专业化经济,并给出了自给自足和完全分工经济的相互转换机制。由于施加了生产函数收益递增和信息完全的强约束条件,杨小凯的模型不能对广泛存在的半分工半专业化现象给出合理解释。通过放松杨小凯模型的假设,在不完全信息、生产者-消费者异质和生产函数收益递减的假设下,讨论分工经济结构的内生性、市场的定价和收入分配功能,发现半分工半专业化经济结构可以在收益递减和异质生产者-消费者的条件下内生出来。由于信息的不完全性和竞争的不充分不完全性,市场的有效性是相对的,只能通过不同经济结构的比较进行讨论。本文在概率意义下通过大数定律和中心极限定理讨论自由竞争市场的有效性(共赢)的条件。Assuming perfect information,producer-consumer homogeneity and increasing returns of production function,YANG Xiaokai developed a theoretical model in which division of labor and specialization were endogenously emerged and the switching mechanism between Autarky and full division of labor economy was given.Due to the strong constraints being imposed,YANG Xiaokai's model could not give a reasonable explanation for the phenomenon of semi-division of labor and semi-specialization existing in real world economy.By relaxing the hypothesis of YANG Xiaokai's model,this paper explores the endogeneity of division of labor,the market pricing and income distribution function under incomplete information,producer-consumer heterogeneity and diminishing returns of production function,and finds that semi-division of labor and semi-specialization can be endogenously produced.Because of information incompleteness,market efficiency is shown to be relative and can only be discussed by comparing different economic structures in the sense of probability.The conditions of efficiency of free competitive market can be represented with the law of large numbers and central limit theorem.
