Spatial and temporal evolution of border trade in Yunnan counties and its influencing factors
Using Coefficient of Variation and GIS spatial analysis,we detected the spatial and temporal evolution and development patterns of border trade in Yunnan counties,analyze the de-velopment pattern of border trade in depth by combining with the model of border trade develop-ment level,and explore the driving mechanism of border trade by using geographic probes.The results show that:① the overall trend of county border trade in Yunnan Province is on the rise,and the total volume varies unevenly among counties,with Ruili City in the west and Mengla County in the south as the representative counties with higher total trade volume,while the over-all trade volume in Ximeng County in the southwest and Lushui County in the northwest is smaller.② From 2010 to 2020,the development pattern of county border trade in Yunnan Prov-ince varies.(3)During the same period,the border trade development in the western and south-eastern border counties is high and the growth rate is stable;the development in the northwestern and southwestern counties is low and the growth is fast;the development in the southern coun-ties is high and the growth is slow.④ The main driving factors affecting the border trade in the counties factors are policy and transportation factors,and the secondary driver is GDP per capita,while there are differences in the driving factors of border counties with different neighboring countries.
