中国区域创新型绿色发展效率测度及其影响因素

The Measurement of China's Regional innovative Green Development Efficiency and Its Influencing Factors

根据研发驱动理论,通过构建包含R&D投入的超效率DEA—SBM模型,分别测算2001—2017年中国不同区域传统型、创新型绿色发展效率及绿色全要素生产率,并借助广义最小二乘法(GLS)模型对区域创新型绿色发展效率影响因素进行实证分析。结果显示:①创新要素下中国及四大经济区域创新型绿色发展效率均高于传统要素下传统型绿色发展效率,呈波动上升趋势,且逐渐收敛。东部地区创新型绿色发展效率最高,西部、东北部地区有所提升,而中部地区并未得到较大提升;②2001—2017年全国创新型绿色全要素生产率呈波动上升趋势,其变化趋势与技术进步变化趋势一致,技术进步是促进其增长的主要因素;③各区域经济发展水平与创新型绿色发展效率正相关,城镇化水平、FDI与全国创新型绿色发展效率正相关,而产业结构和环境规制起负向影响作用。R&D投入规模、R&D投入强度、R&D投入成果与区域创新型绿色发展效率的关系,在全国及四大经济区域有不同的表现。

Based on the research and development drive theory,this paper calculates the traditional and innovative green development efficiency and green total factor productivity in different regions of China from 2001 to 2017 by constructing the DEA-SBM model including R&D input,and empirically analyze the influencing factors of regional innovation green development efficiency by means of generalized least squares(GLS)model.The results show that:①The innovative green development efficiency of China and the four major economic regions under the innovation factor is higher than the traditional green development efficiency under the traditional factors,showing an upward trend of volatility and gradually converge.The traditional and innovative green development efficiency in the eastern region is the highest.The efficiency of innovative green development in the central region has not been greatly improved,while the efficiency of innovative green development in the western and northeastern regions has improved.②From 2001 to 2017,the national innovative green total factor productivity is on a rising trend,and its changing trend was consistent with the trend of technological progress.Technological progress was the main factor to promote its growth.③The economic development level of each region is positively correlated with the innovation green development efficiency.The urbanization level,FDI and the national innovation green development efficiency have a positive correlation effect;the industrial structure and environmental regulation are negatively related to the national innovation green development efficiency.The relationship between the scale of R&D investment,the intensity of R&D investment,the results of R&D investment,and the efficiency of regional innovative green development has different performances in the country and the four major economic regions.
