In view of the uncertainty in the location selection of logistics distribution center for the fresh agricultural products,the present study established a robust model based on the maximization of principal component score taking budget cost parameters as an example.In the process of model solving,the interval form of the uncertain set was used to clarify the constraint conditions,to transform into a certain 0-1 integer linear programming model,so as to solve with the aid of LINGO software.Finally,through studying the location selection of logistics distribution center for fresh agricultural products in the Beijing-Tianjin-Hebei region,it analyzed the application of the robust model and tested the validity of the model. 展开更多

China’s uninterrupted high-speed economic growth depends on promoting the process of industrialization.Based on provincial data during 2003-2016,this paper empirically estimates the impact of labor costs on China’s industrialization and examines its mechanism and path.The results show that the rising labor costs such as wages and social security premiums may lead to China’s“de-industrialization”.With endogeneity excluded,the conclusion still holds.The following policy suggestions are proposed:increasing the effective labor supply in the industrial sector to slow down the increase in wages,implementing social insurance premium reform to reduce social security premium rate,reversing the situation of investment“fl eeing from the real economy and into the virtual economy”in a multi-pronged manner,and optimizing the combination of labor,capital and technology in various ways. 展开更多
