Estimation And Analysis On Influencing Factor Of C_O2Emission Intensity In High Energy Consuming Sectors

Seventy present of our country’s total energy consumption derived from industryduring Eleventh Five-Year Period. In addition, energy consumption of the six highenergy-consuming sectors accounted for77%in total energy consumption ofabove-scale industry. So, the result of energy-saving and emission reduction in highenergy-consuming sectors is important for our country to achieve the goal ofenergy-saving and emission reduction in2020. Based on this background, this paperadopted input-output model as the fundamental theory of research which is aimed toestimate and analysis in the influencing factors of CO₂emission intensity in highenergy-consuming sectors. First of this paper, in order to lay solid foundation to thefollowing study, having introduced and compared the difference and applicationbetween Leontief and Ghosh input-output model. Then, this paper deduced andcalculated environmental responsibility index based on Leontief and Ghoshinput-output model. Chapter4did sensitivity analysis to CO₂emission intensity ofhigh energy-consuming sectors to find out the key production technique coefficientsrespectively based on Leontief and Ghosh model. Chapter5did backward linkagesmultiplier analysis to all sectors based on Leontief input-output model to deeplyinterpret the sensitivity analysis results; at the same time, did forward linkagesmultiplier analysis to all sectors based on Ghosh input-output model to demonstratethe rationality and necessity of the sensitivity analysis results.During the whole research process, this paper inspected and analysed theinfluencing factors of CO₂emission intensity respectively originated from demandand supply angles synthetically using Leontief and Ghosh input-output model. Whendiscussing the problem of sectors’ environmental responsibilities, this paperre-deduced environmental responsibility index which is fit for this research betterdepending on the sectional structure of this paper. One innovation point is doingsensitivity analysis based on Ghosh input-output model which can pick up the keyproduction technique coefficients stemming from the supply side. When doing themultipliers analysis, another innovation point is calculating the final demandmultipliers based on Ghosh input-output model.The main conclusions of this paper include the following several points: a) eventhough high energy-consuming sectors’ direct CO₂emission is huge, the factualenvironmental responsibility of some non-high energy-consuming sectors is muchgreater; b) in most cases, it is more efficient for lowing CO₂emission intensity to improve the production technology of high energy-consuming sectors themselves; c)backward linkages analysis made deeply explanation for the results of sensitivityanalysis based on Leontief input-output model stemming from the demand side; d)forward linkages analysis demonstrated the necessity of improving productiontechnology in some key non-high energy-consuming sectors stemming from supplyside.
