Abstract: Subject to national data and use 2005-2009 year datas for sample, this paper made a comparative study from theoretical and empirical evidence on three data convergence methods including Stark and Geary’s output estimation method, Linear adjustment method and auxiliary regression method about regional and national GDP accounting. Comparison shows :(1) Three methods have its own rationality from theoretical analysis perspective. But we also found that the auxiliary regression method is more than the other two methods in desirability.(2)The convergence of results from the point of view, we found that the auxiliary regression method is superior to the Geary and Stark's output estimation method, the Geary and Stark's output estimation method is better than the linear adjustment method. Due to different methods having its own application, characteristics and convergence effects, we can only concluded that there is only near-optimal method amony three methods while can not clearly determine what methods can be applied to the actual data convergence and can be adjusted to achieve good results.
