ABSTRACT

Foreign Direct Investment (referred to as FDI) is a hot topic for domestic scholars. In terms of FDI-related research in the western region, there are three main ideas: First, it is the impact of FDI on economic development in the western region. Zhang Shenglin and Wu Haiying proposed that FDI in the western region affects economic growth mainly by short-term demand and long-term equilibrium effects;[1] Dou Dengquan proposed that FDI in western region has technology spillover effect on domestic enterprises but has some suppression function in local economic growth.[2] Second, it is the comparative study of different regions. Guo Zhiyi and Yang Xi proposed that FDI has significant technological spillover and capital crowding effect in the eastern region and crowding effect in the central region, without obvious capital crowding effect and technology spillover effect in the western region.[3] He Wenhua has compared spatial differences in the distribution of FDI in the eastern, central and western regions.[4] Third, it is the spatial effect of FDI distribution. He Xingqiang and Wang Lixia proposed that there is significant spatial effect among the FDI in the sample provinces and cities.[5] Tian Suhua and Yang Yechao analyzed the determinants affecting the change of location of FDI in China.[6] There is little research literature about the geographical effects of FDI in the western region. Therefore, spatial autocorrelation model and trend surface model is established in this paper to analyze the spatial aggregation trend of FDI in the western region, which is full of practical significance.
