Abstract: Based on industrial cluster theory, externality theory and industrial efficiency theory, this study measures the logistics industrial agglomeration and industrial efficiency quantitatively,and empirically analyzes conduction path of effect of specialization agglomeration and diversified agglomeration on efficiency of logistics industry. The research shows because of the big regional difference in logistics, the effect of specialization agglomeration on industrial efficiency shows the positive linear relationship, and the diversified agglomeration shows the u-shaped nonlinear relationship; traditional labor, capital and other inputs to logistics industry have little effect, and the effects on the efficiency of the two types of agglomerations are different due to the regional differences. Therefore, we should promote efficiency of logistics industry strategically by advancing the logistics industry agglomeration differently, taking advantage of the logistics industry agglomeration roundly and reasonably adjusting logistics industry structure.
