For the first ten years of China's economic reform process, the internationalisation of the Chinese economy was largely a Pearl River Delta phenomenon, with the export-oriented production of foreign-invested entities based in Shenzhen, Dongguan, and Guangzhou leading the way. In recent years, the development environment for indigenous private-owned enterprises has improved dramatically in the Pearl River Delta Economic Zone and local firms are now playing an ever-growing role in the region's economy. In this regard, Shenzhen, Dongguan, Foshan, and other parts of the Pearl River Delta Economic Zone have been at the forefront of private sector development in China.
