The outbreak of the U.S.financial crisis，happened during 2007-2008，had a serious impacton Zhejiang——one of biggest China's foreign trade provinces.Though all the cities in Zhe jiang share the same trade pattern，the impact to each city shows a huge difference. In this paper，we make empirical analysis on the factors affecting trade development for 10 cities of Zhe jiang from 1997 to 2006 and find that the foreign tradein Zhe jiang depends muchmore on the GDP，the investment in the fixed assets and the industry investment rather than the FDI. This means that the best way to protect itself against the financial crisis is not to depend on the foreign capital but to enhance the competitiveness of its industry.
