The results show that absolute convergence does not exist in rural economics among provinces, indicating that the economics growth of undeveloped provinces is not faster than that of developed provinces. However, the economic development in rural China is characterized by the conditional convergence, that is, if the decisive factors stability is insured, the economic growth of undeveloped provinces would be faster than that of developed provinces. Thus, the disparity among them could be narrowed.
