Abstract: Based on the input-output tables of 31 provinces in China in 2012, using domestic capital flow tables, input output methods and social accounting matrix theory for reference, the inter-provincial trade matrix of China is compiled. The scale and characteristics of inter-provincial trade exchanges in different regions are estimated and analyzed, and the effects of inter-provincial trade exchanges in different regions are compared. The results show that: inter-provincial trade in Beijing and Hainan was highly dependent, while intra-provincial trade in Sichuan and Shandong was relatively large; the total volume of inter-provincial trade in Jiangsu, Beijing was larger, while that in Qinghai and Tibet was smaller; the trade between developed provinces such as Beijing and Shanghai was relatively close, while some central provinces were the main areas of trade inflows; Beijing and Shanghai had strong influence and response, Zhejiang, Jiangsu and other coastal provinces had strong response and weak influence, while Ningxia, Shaanxi and other western provinces showed strong influence and weak response.
