Research On Provincial Carbon Emission’s Efficiency And Influence Factors In China

China is in the rapid industrialization and urbanization development stage, hugepopulation, resource depletion, space requirement of the economic expansion, andeconomy, technology and management level are relatively weak, so China’s energyconsumption and greenhouse gas emission are growing rapidly. China as a responsiblecountry, on the one hand, according to the new constraints, how to ensure economicgrowth is a big question, on the other hand, how to make better use of the opportunityfor the development of low-carbon economy, changing the current extensive mode ofeconomic development about high input, high energy consumption, high pollution, toachieve sustainable development, we should consider urgently. This article is dividedinto seven chapters, introduced carbon emission profiles about China and China’sprovinces, and based on DEA-Malmquist index; it analyzed the efficiency of carbonemissions in China and all the provinces, main influence factors that caused regionaldifference. Then there is a βconvergence test on the carbon emission and its efficiencyamong all the provinces. Finally, drew the following conclusions:First, China’s carbon emissions were sustained growth, there are obviousdifferences in regional carbon emissions, and descending order from east to west,however, Carbon emissions in the western region has grown faster than the eastern andcentral regions. China’s carbon intensity decreased gradually, regional carbon intensityis quite difference, increasing gradually from east west, and this difference is stillgradually expanding, This is because the central and western regions undertake theeastern region’s “high-carbon” industry.Second, the efficiency of China’s carbon emissions is improving, mainly due totechnical progress; the technical efficiency of carbon emissions is declining, mainlycaused by the decline of the pure technical efficiency.Third, from1995to2009, carbon emissions of all provinces in China have growth,but the growth rates in the provinces are different, most of the low-ranking provinces’carbon emissions are growing faster than forward-ranking provinces. This is due toeconomic growth rate and growth mode, industrial structure, energy consumptionstructure and the level of technical development in the provinces.The carbon intensity in economically developed provinces tend to be lower,economically less developed provinces tend to be higher, this is because the carbon intensity of the province is related with the stage of economic development and thelevel of industrial development, and not linked with economic aggregate.Fourth, China’s provincial economic growth rate is faster than the growth rate ofcarbon emissions.Fifth, efficiency of carbon emissions in most provinces of China is improving, butthere are some differences, mainly influenced by the level of technical development inthe provinces, the impact of technical efficiency in carbon emissions is limited, and thetechnical efficiency of carbon emissions is decided by the pure technical efficiency.The technical progress index in economically developed provinces is higher thanthe economically less developed provinces, and the technical efficiency is lower thanthe less developed regions. So the developed areas are of significant “Frontier ShiftEffect”, and the less developed areas are of significant “The Catch-up Effect”.Sixth, China and its central region’s carbon emissions are absolutely βconvergent,but the absolute βconvergence trend in eastern and western regions is not significant.China and its three regions’ carbon emissions are all absolutely βconvergent, mainlyaffected by the level of economic development, the adjustment of industrial structure,the changes in the structure of energy consumption in varying degrees.China and its three regions’ efficiency of carbon emissions are relativelyβconvergent. China and its central and western regions’ efficiency of carbon emissionsare relatively βconvergent, mainly affected by technical progress and technicalefficiency in varying degrees.
