Abstract: This paper constructs a new industry relocation measurement model, calculating the scale and path of China's domestic and international dual IR from 2002 to 2017, and evaluating the economic impacts of historical and potential IR. Results show that over the past decade, the IR scale from abroad to the southeastern coastal areas of China has significantly decreased, while the IR scale to central and western regions has increased modestly. The overall IR scale from abroad to China has decreased. China's domestic and international IR occurs concurrently, with the former emerging as the dominant mode in recent years. The main path of domestic IR in China is from the southeast coastal regions to the central and western regions. The value-added gains of China from international IR are gradually reduced. The outflow of labor-and technology-intensive industries would harm China's economy in the short term. However, actively promoting the central and western regions to undertake IR from eastern regions would significantly alleviate the negative impact.
