Abstract: This paper examines the effect and transmission channels of the organization change in Goldwind Sci & Tech on the stock returns by using the event study method and VAR model. First, the empirical results show that the abnormal returns (AR) and the cumulative abnormal returns (CAR) in the short run are not significant, indicating that the organization change has no significant effect on the returns of Goldwind Sci & Tech. Second, and more interestingly, the CAR in the long run is positive and sometimes becomes significant, implying that the organization change has a positive effect on the development of Goldwind Sci & Tech. Particularly, it is reported that the development of Goldwind Sci & Tech is significantly higher than the industry level, indicating the important role of the organization change. Finally, the operating income has a positive effect on AR, and the operating expenditure has a negative effect, indicating that the operating income and expenditure are two important channels affecting the returns.

Key words: organization change, event study, abnormal returns, M-estimate
