摘要
This study uses two different datasets to explore the stylized facts of interprovincial trade in China during the recent two decades. One dataset provides the magnitude of bilateral interprovincial goods trade calculated using firms ＇ value-added tax invoices. The other supplies estimates of interprovincial trade using provincial input-output tables. We find that China has both a large value and a high growth rate of interprovincial trade, but there still exists a home bias in internal trade for most provinces. In addition, disaggregation by product shows that the manufacturing sector has the largest share of interprovincial trade and this share continues to grow. Finally, the spatial distribution of trade suggests that all provinces can be clustered into a smaller number of trade areas with large intra-cluster trade. Therefore, China＇s central government should make more effort to reduce local protection, stimulate domestic demand and coordinate interregional trade among local jurisdictions.
