摘要: 流通是从纵向上看的总体的交换，每一个交换环节、每一种商品的交易效率的提高必然会带来社会经济运行节奏的加快，即流通效率的提高。本文通过模型分析和实证研究，得出如下结论：流通效率的提高因为减少了各种各样因为耽搁迟滞带来的产出损耗而加快了资本积累和经济收敛的速度并且提高了平衡增长路径上的人均产出。人均产出的增加进而又提高了下期的交易效率。因此，交易效率和流通效率的相互作用是一个正反馈过程。我国西部地区要想缩小与东部地区的经济差距，在推行城市化战略时必须加大投入发展流通，提高流通效率。

  Abstract: Circulation is the whole exchange in the vertical view. The social economy circulates faster due to the fact that the transaction efficiency of each exchange part and each commodity advance, namely, the improvement of circulation efficiency. Based on the model analysis and positive study, this paper concludes as follows: the improvement of circulation quickens the velocity of capital accumulation and economic convergence and furthermore enhances the output per worker in the balanced growth path because of the fact that it can reduce the loss of output. The augment of the output per worker can enhance the transaction efficiency of the next term. Consequently, the reciprocity between transaction efficiency and circulation efficiency is a positive-feedback process. In order to reduce the economic gap with the eastern region of China, the poor western should develop commodity circulation and advance the circulation efficiency with many more inputs in the urbanization process.

  Key words: urbanization; transaction efficiency; circulation efficiency; economic convergence; positive feedback.
