有偏技术进步下的要素替代与物流产业增长

Factor Substitution and Logistics Industry Growth under Biased Technological Progress

文章采用1978-2014年省级面板数据,测算了中国各地区物流产业的替代弹性,并在此基础上对物流产业要素替代弹性与产业增长之间的关系进行了研究。结果表明,中国物流产业的要素替代弹性大于0且小于1,各地区要素替代弹性存在一定的差异并呈东高西低的分布格局。要素替代弹性与物流产业增长呈正的相关性,要素替代弹性的提高有助于物流产业的发展。因此,应重视要素替代弹性对物流产业发展的作用,这为缩小物流产业的区域差异提供了可能。

Based on provincial panel data from 1978-2014,we estimate the elasticity substitution of logistics industry in various regions of Chinese,and then research on the relationship between the elasticity substitution and logistics industry growth. The results show that the elasticity substitution of logistics industry in China is more than 0 and less than 1. There is difference among regions of the elasticity substitution and the elasticity substitution of the East is higher than the West. There is positive correlation between the elasticity substitution and the growth rate of the logistics industry,the increase of the elasticity substitution is helpful to the development of logistics industry. Therefore,we should pay more attention to the elasticity substitution in the development of the logistics industry,which provides the possibility to reduce the regional differences of the logistics industry.
