Abstract: This paper first briefly introduces the current situation of wood export in China. By analyzing the export scale, market share, structure of the export products and the main export markets, it reveals the rapid growth of wood export since China's entry into WTO. Then based on the constant market share model (CMS model), and from the three dimensions of demand, structure and competitiveness, it makes an empirical analysis of the effects and tendency of the influencing factors that lead to the export growth of China's wood floor from 2001 to 2011. Finally the following conclusions are derived: China has a relatively high dependence on the expansion of the target export markets, and a relatively low trade concentration of target markets and new wood floor species which have rapid growth of demands. The structures of export products and market of wood floor in China didn't adapt well to the changes of target markets. To promote the export development of wood floor in China, we should optimize the structures of export product and market, improve the quality of the products, change the mode of competition, and improve the market information service.
