Abstract:Based on the absolute β-convergence of Baumol model, this paper calculate a comprehensive scientific and technological input level index with 8 representative indicators at first.Then this paper study the convergence of the 30 provinces except Tibet Chinese mainland area from 1996 to 2014. No matter the whole country, or in the East, the Middle or the West, there is a common law and a trend. That is in the early stage the β-convergence is significant, but along with the time , the divergence is more and more strong. Although only the spatial autocorrelation is significant in the whole country, Considering the spatial factors the significance is improved and the value of β is increased , that is to say the divergent stronger. So if we want to enhance the balanced development of regional economy, balanced development to take measures to promote the comprehensive investment in science and technology is crucial.
