Research On The Sources Of Change On CO₂ Emission In Zhejiang

Global warming problem cause world-wide attention for its nagetive effect on people's life and production.people start to doutle of the economical pattern in which fossile energy is used as power, the international society have signed a series of treats to deal with carbon mission,and to reduce carbon dioxide mission have become the international consensus,as a result, low carbon economy was proposed.Nowdays low carbon economy has become one hot point of acdemical research,and there were many studing literatures about this problem.But the study of the economist pay more attention on the whole country,while development imbalance of the region as one feature of china,which make the situation of the regions very different,so the present study is not very useful to instruct the region.Meanwhile it has some defect in analyzing method for factor decomposition to study the driving force of industrial structure change.First the paper reviewed the present achivement of study ,then for the problem that lies in the previous study ,the paper applies two-tier KLEM input-output structural decomposition model (KLEM I-O) and weighted Shapley value to analyze the sources of change on CO2 emissions and its causing factors in zhejiang over the 1998-2006 timeframe from the situation of zhejiang province,after the paper reached some conclutions of importance,so as to give some suggestions for economic development of zhejiang.The figure shows that it has great links between economic growth and CO2 emissions,meanwhile industrial structure, structure , subsituation and technical change effect are important factors that affect CO2 emissions.Of which industrial structure and energy structure are basic factors.it tells that it has to upgrade industrial structure and improve efficiency of energy use in order to reduce CO2 emissions.
