Research On The Construction And Price Strategy Of Rural Biogas Suuply Chain Based On Carbon Emission Reduction

Developing rural biogas to promote carbon emission reduction is significant under the situation of global response to climate change.It can not only recover methane by changing the way of livestock waste management,but also provide clean energy. Following a decade of expansion, some obstacles referd to carbon emission reduction of rural biogas are emerging such as uncompleted structure and discoordination of rural biogas supply chain although its rich experiences. Under the background of that national carbon market is about to kick off in 2017,it is urgent to solve these problems of rural biogas supply chain.The dissertation put forward the concept and connotation of rural biogas supply chain, systematically summarized its type and mode in jiangxi province as an example, construct the new rural biogas supply chain based on the carbon emission reduction, compiled GHG emissions listing of agriculture in jiangxi province by acknowledged methodology, discussed the GHG emission space-time characteristics of jiangxi swine production and potential of carbon emission reduction in rural biogas, empirically analyzed the key factors of carbon emission reduction in rural biogas, studied the pricing strategy in new rural massive biogas supply chain of three different recycling mode,built the game model of pricing strategy in rural biogas power generation supply chain within the price under the random. The main content was divided into several parts as follows.The first part put forword the concept of rural biogas supply chain based on the research reviewed at home and abroad. Its characteristic was given after the research background and meaning was put forward as well as technical route and research method.Then the new household biogas and massive biogas suuply chain based on carbon emission reduction were built,the different pattern of massive biogas suuply chain including upstream, midstream and downstream were illustrated.The second part compiled the listing of GHG emissions in agriculture. The calculation and analysis for the distribution characteristics of methane and nitrous oxide emissions in Jiangxi provinces pig-breeding was given,then its carbon reduction potential was also discussed.The results shows:there are 34.3274 million tonnes of carbon dioxide-equivalent in agriculture in 2012.It including four aspects: rice paddies methane emission 15.1907 million tonnes, farmland nitrous oxide emission 8.3313 million tonnes, animal gut fermentation methane emissions5.9784 million tonnes, animal waste management methane and nitrous oxide emission4.8269 million tonnes. The methane and nitrous oxide emissions in Jiangxi provinces pig-breeding went up from 2.714 million tonnes in 2004 to 3.788 million tonnes of carbon dioxide-equivalent in 2013.The third part gave the empirical research in Jiangxi province rural biogas carbon emissions reduction. Firstly, the case study of Jiang Jian household biogas and huideneng massive biogas carbon emissions reduction were given which their data of carbon emission reductions was calculated. Secondly, an empirical analysis of key factors to carbon emission reduction in rural biogas was made in which the dependent variable was defined as rural biogas energy production and forteen independent variables was assumed. The stepwise regression analysis model was constructed in which the data of Jiangxi biogas from 2005 to 2012 was put. It provided scientific basis for rural biogas carbon emissions reduction by the model result that the key fators were list according to the degree in turn: pig number on hand in year-end, technical service personnel number, pig number on column in year-end and the government subsidies.The forth part focused on the price strategy game of rural massive biogas suuply chain on the condition of that energy prices are determined or flexible such as electricity and biogas.It built the recycle price strategy model and the improved model of contract of rural massive biogas suuply chain respectively, comparatively analyzed the recycle price strategy and income-cost sharing contract optimization under the condition of centralized decision-making and decentralized decision making which including manufacturers recycling mode, the third party recycling model and mixed mode of rural massive biogas suuply chain. Finally the numerical simulation is also made.The fifth part focused on the price strategy game of rural biogas power generation supply chain under the condition of random carbon price.Firstly, characteristics of carbon trading market and price was discussed,then the strategy between farming enterprises and energy producers were given not only on the condition of continuous selection but also discrete selection.The numerical interval of recycle price and carbon price were researched refer to the three kinds decision of farming enterprises behavior strategy respectively which including being a power suppliers, selling part of the wastes and selling all the wastes.In summary, the dissertation focused on the construction and price strategy of rural biogas supply chain based on the perspective of carbon emission reduction.It studied on this topic both in theory and experience by the introduction of carbon trade.The construction of rural biogas supply chain, status and potential of carbon reduction,key factors and price strategy on different conditions were analyzed.These study work can provide a reference basis for the government and stakeholder to develop rural biogas and promote carbon emission reduction.
