经济发展水平对沼气工程的影响

Impact of Economic Development Level on Biogas Projects

文章通过2007~2015年省级面板数据,建立对数回归模型和门槛回归模型,验证经济发展水平对沼气工程的影响。得出:经济发展水平是对沼气工程建造规模影响最大的因素,同时,养殖规模、政府能源经费投入等因素同样对沼气工程的建造规模有正向作用;产气总量则主要由建造规模决定,因此经济发展水平的影响是间接性的;产气率在不同的经济水平下存在明显的差异。回归结果反映了一些沼气工程发展中存在的问题,对此文章提出了相应的政策建议。

In this paper,the provincial panel data from 2007 to 2015 was used to establish the log linear regression model and threshold regression model for verification of the impact of economic development level on biogas projects. The results showed that the economic development level was the most important factor influencing the scale of biogas project construction,and the factors such as farming scale and government energy investment also played a positive role in the scale of biogas project construction.The total gas production was mainly determined by the construction scale,so the influence of the economic development level was indirect. There were obvious differences in gas production rate at different economic levels. The regression results reflected the problems existing in the development of some biogas projects, and some policy suggestions were put forward accordingly.
