Low Carbon Effect Of Technological Progress And Its Spatial Differences

Since reform and opening,China's economy has developed by leaps and bounds.With the continuous improvement of industrialization and urbanization,problems such as waste of resources and environmental pollution have become increasingly serious.Carbon dioxide emissions have increased,and China has become the world largest carbon dioxide emitter.The Chinese government has successively issued a number of environmental-related policy documents and made emission reduction commitments.However,technological progress is the fundamental driving force for promoting low-carbon development and an inevitable choice for achieving sustainable development.Based on regional economics and energy economics,this paper empirically analyzes the spatial impact of four different sources of technological progress on carbon emissions efficiency,and selects the appropriate technological progress for regional low carbon development.Firstly,according to the definition of technological progress concept,this paper divides technological progress according to different sources: original innovation,imitation innovation,direct introduction and indirect introduction,and studies the mechanism of the influence of technological progress from different sources on carbon emissions.Secondly,on one hand,the Super-SBM model is used to calculate the carbon emissions efficiency.On the other hand,the entropy method is used to fit the technological progress to explore the development status of China's carbon emissions and technological progress.Secondly,this paper uses the spatial Dubin model(SDM)to analyze the spatial effects of four different sources of technological progress on carbon emissions efficiency.From the perspective of country,original innovation,direct introduction and indirect introduction are all conducive to improving carbon emissions efficiency,but the impact of original innovation on carbon emissions efficiency is not significant;direct introduction curbs the efficiency of carbon emissions in the region;imitation innovation leads to lower carbon emissions efficiency.Therefore,for China's overall development,the introduction of technology with indirect introduction is the optimal technological progress for low carbon development.Thirdly,according to the characteristics of China's carbon emissions and technological progress,it is carried out separately for the eastern,central and western regions.Furthermore,the threshold model is used to explore the path of technological progress which is suitable for low-carbon development in different regions.The eastern region is mainly developed areas such as the Yangtze River Delta,the Pearl River Delta and Beijing-Tianjin-Hebei.The awareness of energy-saving and emission reduction of technological innovation is strong.The digestion,absorption and reference of advanced technologies are only an auxiliary part of regional development.Thus,the eastern region adopts the path based on original innovation and indirect introduction,and the original innovation should achieve R&D expenditure intensity greater than 0.35,and indirect introduction should be maintained between 0.5240 and 0.7349 in FDI per unit GDP.The central region,which is in the stage of rapid development of industrialization and urbanization,has undertaken industrial transformation in the eastern region.The technological innovation is relatively small.Increasing the introduction of technology is an important way for low-carbon development in the central region at this stage.Therefore,the central region adopts direct introduction,and the limitation of the foreign technology import contract should be maintained between 4.9998 and 31.9989.The western region is limited by geographical location,which economic development is very backward.In the west,technological innovation focuses on production,which has a restraining effect on carbon emissions efficiency.Compared with its own technological innovation,technology introduction is more suitable for the development speed of the western region.So,the western area adopts direct and indirect introductions,and the direct introduction of foreign technology import contracts should be less than 154.0073.Finally,on the basis of the research on the impact of technological progress on carbon emissions efficiency,from the perspective of technological progress and regional development,this paper makes suggestions for low-carbon development: making full use of regional advantages and implementing differentiated technology development policies;optimizing technology introduction structure and increasing independent innovation capability;creating technology spillovers actively and strengthening regional technical cooperation.
