交易效率、贸易条件与经济发展

Transactional Efficiency,Trade Condition and Economic Development

通过对一个有交易成本的李嘉图贸易模型进行超边际分析,证明一国均衡的综合生产力和人均真实收入水平的提高,并不完全受制于贸易条件恶化的影响。在衡量一国经济发展状况时,相对于贸易条件来说,交易效率的提高对一国经济的发展更为重要。忽视其它相关条件,盲目地认为随着一国贸易条件的恶化,该国将从贸易中得到的好处下降的看法,具有一定的误导性。

Through inframarginal analysis on a Ricardian trade model with transaction cost, this paper confirms that the growth of balaneed integrated productivity and per-capita net real income in one country is not totally determined by the worsening of trade conditions. Compared to trade conditions, the growth of trade efficiency is more important to economic development of one country considering its economic development conditions. Hence, it is misleading to some extent to think that the profits of one country earned from trade will decrease if the trade conditions of this country are worsening, but other relevant conditions ignored.
