科技进步对经济增长贡献率分析——基于山东省1978~2017年数据的实证分析

On the Contribution Rate of Scientific Development to the Economic Growth——The Empirical Data Analysis of Shandong from 1978 to 2017

通过对山东省1978~2017年全省生产总值、固定资产投资规模和相关就业人数数据的整理,利用C-D生产函数模型及Solow余值法评估科技进步、资本投入和劳动投入对山东省经济增长的贡献率.其结果充分显示:科技进步和资本投入增长是拉动山东省经济增长的主要引擎,其贡献率分别占比为41.07%和43.9%,然而劳动的投入对山东省的经济增长贡献率较低.科技进步对经济拉动的贡献率逐年上升,其对经济贡献率已成为推动山东省经济增长的主要力量.

This paper collates the data of Shandong's GDP,fixed asset investment scale and related employment from 1978 to 2017,and evaluates the contribution rate of scientific and technological progress,capital investment and labor investment to the economic growth of Shandong by using the C-D production function model and the Solow residual value method.The results show that scientific and technological progress and capital investment growth are the main engines of economic growth in Shandong,and their contribution rates are 41.07%and 43.9%respectively.However,the contribution rate of labor investment is relatively low.The contribution rate of scientific and technological progress to economic growth is increasing year by year,and it has become the main force to promote economic growth in Shandong.
