Economy Primary industries Primary productions are agricultural, such as rice, lychee, banana, and sugar cane. Added to this, horticulture in Xiaolan Town is famous throughout southern China for its blooming chrysanthemum and chickens. Manufacturing industries Zhongshan, Dongguan, Nanhai, and Shunde are dubbed the 'Four Little Tigers' in Guangdong. The proximity of Zhongshan to Hong Kong and Macau is an advantage to its economic development, especially in manufacturing. In the 1980s, Zhongshan had a relatively developed state-owned enterprise (SOE) sector that was used to stimulate Township and Village Enterprises (TVE) development in the countryside. Currently, the SOE sector is much weaker, and the economy is dominated by foreign investment and TVEs, and by specialized 'manufacturing towns'. Each of these towns specializes in making a particular product. Most of the towns have earned a reputation as leading manufacturers in their pillar industries. These specialized manufacturing towns include: Dachong Town for mahogany furniture Dongfeng Town for electric household appliances Guzhen Town for lighting fixtures Huangpu Town for food processing Shaxi Town for casual wear manufacturing Xiaolan Town for locks and hardware, as well as for electronic acoustics products The government of Zhongshan encourages "Research and Design" in the region by setting up national level research centres and specialized industrial regions. For example, the Zhongshan National Torch High-Tech Industrial Development Zone () was established in 1990 in the east of the city by the Ministry of Science and Technology and the governments of Guangdong province and Zhongshan. Zhongshan Port, which ranks among the top 10 ports nationwide in container-handling capacity, is in the zone. Since 2001, it has included the Zhongshan Electronic Base of China () for its reputation in the electronic acoustics industry. Following possible development in Nansha, the city considers its eastern part, of which of land is available, a focus of future development. Currently, the city is trying to re-organize its fragmented industrialization. Meanwhile, the light and labour-intensive industry characteristic of the local economy faces the problem of a shortage of land in Zhongshan. Tourism, recreation and leisure Two natural hot spring resorts are located in Sanxiang Town, such as the national own firm Zhongshan Hot Springs Resort, which is ranked top 10 hot spring resorts in China because there is a rare hot spring reservoir in the Pearl River Delta.
