From the development trend and rate of world photovoltaic (PV) industry and the difference between China and the world and the challenge faced by getting into WTO, this paper analyzes the development strategy and rate of China's PV industry which should be adopted. The analysis shows that world PV industry development will speed up with an average increase of 28.5% during 2000 - 2010. If china can seize the opportunity of “getting into WTO” to speed up its PV industry with an average increase rate of 35% per year during the same period, the Chinese PV Industry may catch up with world average level in terms of the cost of PV electricity. The preliminary prediction of the development in the earlier stage of 21st century and the analysis of driving measures for realizing the strategy plot are made in this paper as well.
