- Abstract：This article describes the regional economic gap and its restrictive factors on harmonic development in rural China.Based on data recorded between 1992 and 2003,it examines the(absolute or conditional) convergence of regional economic growth by estimating 3 models based on the New Classical Economics.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.This paper shows that the manpower capital,the industrial structure and agricultural science and technology play an important role in the process.Keywords：rural China,regional economic gap,unconditional convergence,conditional convergence1|6|0<HTML><L-PDF> <Meta-XML>Updated：2024-02-27
