摘要
技术进步是推动碳生产率提高的重要因素,但体现式和非体现式技术进步对碳生产率的影响存在差异。本文以中国1985-2012年的时间序列数据为样本,基于索洛余值模型构建状态空间模型对东、中、西三大区域的体现式和非体现式技术进步进行测度,并探究两种形式的技术进步对碳生产率的影响,最后进行区域比较。结果表明:长期来看,各区域不管是体现式技术进步还是非体现式技术进步,均可使碳生产率水平得到提高,但非体现式技术进步对碳生产率的促进作用更明显;短期内,三大区域的体现式技术进步对碳生产率均有着负向影响,而非体现式技术进步对碳生产率的影响存在差异,其中,东、西部地区呈正向影响,而中部地区呈负向影响。本文结合各区域的实际状况提出了政策建议。
Technological progress is an important factor to increase carbon productivity,but the influences of capital and non-capital embodied technology progresses on carbon productivity are different.Based on the time series data during 1985-2012,capital and non-capital embodied technology progresses were calculated and the influences of capital and non-capital embodied technology progresses on regional carbon productivity were explored.The empirical results indicated that in the long run,technology progresses raised the level of carbon productivity no matter they are capital and non-capital embodied;in the short term,it was ubiquitous that the capital embodied technological progress would reduce the carbon productivity.To be specific,non-capital embodied technological progress had a positive effect on carbon productivity in the East and Wes;however,in the Middle,non-capital embodied technological progress had a negative effect on carbon productivity.Finally,this paper recommended some policies based on the actual situation of each region.
