Plarization, New Polarization and Zhujiang River Delta's Development

Since reforming and opening to outside world, the Zhujiang River delta has absorbed an amount ofcapital, technology and labor forces with favorable policies and adaptable approaches, forming polarization effectswith a labor-intensive as a core. Driven by polarization effects, the Zhujiang River delta has undertaken great re-gional changes, which include: 1 the main economic figures increasing rapidly and economic strength becomingstronger and stronger;2 light industry and labor-intensive industry polarization; 3 the proportion of second andtertiary industry in GDP increasing while agricultural proportion decreasing. 4 rapidly urbanization; 5 regionalstructure adjusted.However, since the middle of the 1990s, the polarization in the Zhujiang River delta has weakened becauseof some changes from home and abroad, which are: 1 with the advantages of favorable policies lost, internalforces weaken; 2 stronger competition from Shanghai and Sandong Province; 3 external economic environmentchanges due to Asia financial crisis and lessening investment from Hongkong and Macao; 4 fierce challenges tolight industry and labor-intensive industry because of increasingly product cost.

But, there exists somelimitation, such as lack of well-quality talents, technology, so some measures must be taken to settle down thisproblems.
