Quantitative analysis of relationship between Beijing scientific and technological progress and economic growth

Science and technology are the primary productive forces.In order to know the role of scientific and technologcial progress and its influence on the economic development of Beijing,the contribution rate of scientific and technological progress to economic growth in Beijing is estimated.First,by using generalized C-D production function model,Beijing's GDP from 1980 to 2011 is treated as the output,fixed assets investment as capital input,the number of employment as labor input.Then the time series of scientific and technological progress are introduced to the model to estimate the capital and labor elasticity coefficient.Last,the contribution rate of scientific and technological progress is measured based on Solow residual method.Results show that the elasticity coefficient of capital and labor are 0.266 6 and 0.733 4 respectively.The scientific and technological progress contribution rate is 59.33% on average,playing a main role in economic growth of Beijing.
