ABSTRACT=The logistics and manufacturing industries are basic industries that support social development. This paper classifies the carbon emissions from the logistics industry and pollution emissions from the manufacturing industry as undesirable outputs, evaluates the ecological efficiency of the logistics and manufacturing industries in the Yangtze River Delta from 2006 to 2016 by using the unexpected slacks-based measure (SBM) model, then analyzes the spatial differences in industrial correlation efficiency by using the exploratory spatial data analysis method. Then, the spatial econometric model is used to analyze the driving factors of the linkage ecological efficiency between logistics industry and manufacturing industry. Finally, the linkage ecological efficiency is predicted. The results show: (1) The efficiency of the manufacturing industry in the study area has steadily improved. The efficiency of the logistics industry fluctuates and rises. The level of the industrial linkage development between the logistics and manufacturing industries is high. (2) The results of the spatial heterogeneity analysis show that the linkage development efficiency of the logistics and manufacturing industries is high, and the spatial differentiation of high-high agglomeration and low-low agglomeration is obvious. The spatial agglomeration characteristics are relatively stable, and the spatial diffusion effect is strong; the linkage efficiency presents the development trend from multiple agglomeration areas to one agglomeration area in space. (3) The results of driving factor analysis show that foreign direct investment, government intervention and human capital have positive effects on linkage ecological efficiency, while industrial structure, environmental regulation and energy intensity have negative effects on linkage efficiency. (4) The results of the linkage development trend analysis show that the linkage efficiency of the two industries will tend to be stable in the future.
