Against the background of a complex and evolving statistical system, this article addresses three crucial issues in the understanding of the rapid export expansion of China in general and the Pearl River Delta in particular. First, the export orientation of the Pearl River Delta is critically assessed. The gradual emergence of export-oriented firms in the region and their spatial clustering around Hong Kong are highlighted. Secondly, the structural dimension of export expansion in the region is examined. Foreign-invested enterprises were found to be the “engine of growth.” Lastly, an analysis of the spatial dimension of the foreign-invested enterprises' export component reveals that the juridical status and geographical locations of exporting firms are complementary in providing a better understanding of export expansion in China since 1978.
