摘要
物流产业集中度高低的价值判断必须依据物流产业的运行效率来进行。影响物流产业集中度的主要因素包括规模经济性、市场需求量、企业进入壁垒、产品差异化水平和技术进步、产业政策。其中市场需求增长率和企业进入壁垒两个变量与集中度是负相关关系,且市场需求增长率对集中度的负向影响最大,需将物流市场规模的增长控制好,以防增长过快导致集中度下降。其余三个变量(规模经济性、产品差异化水平和技术进步、产业政策)与集中度的高低成正相关关系,且规模经济性对集中度的正向影响最大,所以扩展物流企业规模是提高集中度的有效对策。
Value determination fro intensity degree of logistics industry must be based on its operating efficiency. Main factors influencing intensity degree of logics industry include, scale economy, quantity of market demand, entrance barriers for enterprises, disparity level of products, technological improvement and industry policies, among which, increasing rate of market demand and entering rate of enterprises are two variables negatively correlating with intensity degree, while the former has more negative influences. The scale increase of logistics market must be well controlled in order to prevent too quick increase resul- ting in decrease of intensity degree. The other three variables are positively correlated with intensity de- gree, and scale economy has the most influences. So expanding scale of logistics enterprises is the effective policy for enhancing intensity degree.
