The Research On Forestry Biomass Energy Development And Utilization And The Construction Of The Industry Supporting System

As an important part of biomass energy, the development and utilization of forest biomass energy have received great attention in the world and became a significant global strategic resource in future. At present, the development of the biomass energy is entering a mature period in America, European Union and some other developed countries. For example, the development of the bio-fuel ethanol and bio-diesel had realized industrialization, which does help to relieve the lack of energy, improve ecology environment and increase farmers'income to a certain extent. By contrast, the development and utilization of forest biomass energy have received great attention in China in recent years, however, the development of the industry still at the start stage that have gap to industrialization owing to the limit of the late start, small scale and technological innovation. For example, the development of forestry bio-solid fuel, forestry bio-liquid fuel and forestry bio-generation is still facing many issues, especially in material shortage, which makes certain scale energy source forestry cultivation become a key problem. Focused on the utilization of forestry biomass energy and the development of the industry, on the background of energy security and food security, based on related principles of agricultural economics, sustainable development economics, game theory and information economics, and according to the game model between enterprises and foresters, the farmer decision-making model and the Logistic regression model, the research in the thesis analyzed influence factors during the development of forestry biomass energy and proposed three support systems to stimulate the industry grows, which include policy support system, technical support system and market support system. The main contents and results are as follows:Firstly, the dissertation studied the status of the development and utilization of forestry biomass energy. The research shows that it's urgent to develop the forestry biomass energy since it has become an effective way to coordinate energy security and food security. The development of the forestry biomass energy, such as forestry bio-solid fuel, forestry bio-liquid fuel and forestry bio-generation, has certain superiority in resource and technology, in addition, some projects have entered demonstration stage. However, there are many issues on overall development of the industry which lead to the industry is still at the start stage and have large gap to industrial, such as unsound legal system, market circulation blocking and investment and financing system imperfect. Therefore, the dissertation proposed that recognize the relationship among the behavioral agents in the industry and the influence to the project would do help to achieve virtuous circle and quickly development.Secondly, construct a game theory analysis of behavioral agents among the development of forestry biomass energy. The development process of forestry biomass energy is an industry chain which contain many links, e.g. seed selecting, planting, management, picking, purchasing, transportation, storage, processing and sells. Under certain industry development mechanism, the government, enterprises and foresters would interact and affect each other. Moreover, it's impossible that the development of the industry depart from any behavioral agent since any decision of the behavioral agent is vital to the project. The result of the game theory analysis of enterprises and foresters showed that a necessary condition of the energy source forestry cultivation is the participation cost should lower than utility, namely the bigger the values of U11-U10 and U21-U20, the higher expected utility that enterprises and foresters get in the project. Further more, the project as a Nash Equilibrium would be accepted by enterprises and foresters, meanwhile, a Pareto Improvement is reachable.Thirdly, empirical analyses on foresters participate in the development of forestry biomass energy. Based on a survey of 182 households in Gucheng and Yichang in Hubei province, the dissertation analyzed influence factors during the development of forestry biomass energy with the Logistic regression model. The result shows factors such as sex, age and education had little influence on the project, while external environment variables greatly affected and became main factors to the project, especially subsidies, propaganda and guidance from the government. Thus, there are two ways for the government to promote the development of forestry biomass energy. On the one hand, it's necessary for the government to establish preferential policy to attract investors and ensure products distribution in order to remove foresters'worries. And on the other hand, the government should step up publicity to encourage the participation of the foresters. Furthermore, it's essential to correct awareness on conventional energy development and environmental protection of the public so as to prevent the large-scale pull out at once when the expected benefits unreachable in future.Fourthly, analysis on the government participates in the development of forestry biomass energy. It was found that influences of policy factors to the development of the industry are different based on the unique target system and the multi-objective system. Under the multi-objective system, the development of the industry may affect associated industry for different policies from the government to different industry. For example, the development of forestry biomass energy industry was directly affected by a bio-liquid fuel subsidy policy, which was made under the condition of petroleum resource shortage. Consequently, in order to promote and support the development of emerging industry, government should pay attention to coordinate the relationship of different industries when making relevant policies.Fifthly, construct industry supporting system of forestry biomass energy. Based on analysis of series policy guarantees of the development of forestry biomass energy in foreign countries, the thesis proposed industry supporting systems construction of forestry biomass energy, which includes policy support system, technical support system and market support system. In the market support system, the paper pointed out rural area location of the industry development particularly and the conclusion of agricultural energy. Furthermore, taking the province as the research object, the thesis graded the forestry biomass energy market and proposed a development mode of forestry biomass energy industry, which is consisted of "government+corporate champion" forestry-electric unionization mode, "government+cooperative organization+enterprise" mode and "government+industrial group" forestry-oil unionization mode.
