英文摘要：

This paper analyzes the factors which affect the hedging behavior using data of the listed firms from 2005 to 2010 and tests the costs of financial distress theory and other existing theories. The authors find that the motives of using currency derivatives include indicators of financial status investment opportunities and so on, which is consistent with the authors＇ assumptions. The paper also analyzes the relationships of the proportions of managerial ownership, property rights, the market indexes and political connection of firms with derivatives. The robustness test using continuous dependent variables supports these conclusions. The paper expands the research of motivations of foreign exchange derivatives and makes corresponding recommendations on regulating derivatives information disclosure of listed companies and strengthening regulation of corporate derivatives behaviors.
