生态文明建设对我国的经济发展质量与速度、对我国的社会建设提出了更高的要求,以科技创新为前提的生态文明建设已成为实现我国经济社会良性发展的必由之路。文章在C-D生产函数的基础上引入科技投入变量构建生产函数模型,采用2003年至2012年数据估计全国生产函数,确定科技等投入对生态GDP产出的贡献率,得出科技投入对生态文明建设的有显著的正向作用,同时也证明了我国经济发展已越过生态拐点,进而转入生态文明经济发展的新阶段。
The construction of ecological civilization has put forward higher requirements on the quality and speed of economic development in our country and on the social construction in our country. The construction of ecological civilization based on the scientific and technological innovation has become the only way to realize the sound development of our economy and society. Based on the CD production function, the article introduces the input variables of science and technology into the production function model, and uses the data from 2003 to 2012 to estimate the national production function to determine the contribution rate of science and technology inputs to the output of ecological GDP. It also proves that our country’s economic development has crossed the turning point of the ecological system and then shifted to a new stage of ecological and civilized economic development.
