⑴ Background——Poverty and ecological civilization construction are the realistic problems that all countries in the world need to face in their development. China has put forward the concept of green development and implemented the major strategy of targeted poverty alleviation. Ecological poverty alleviation is the combination of poverty alleviation and development and ecological protection measures in order to achieve sustainable development in poor areas. Forestry ecological poverty alleviation is an important part of ecological poverty alleviation policies in China. It is of great significance to discuss the impact of forestry ecological poverty alleviation on farmers' income for the evaluation of policy effect. ⑵ Methods——The western region of China has overlapping characteristics of ecological vulnerability and poor mountainous areas. Based on the statistical panel data of 12 provinces(municipalities, autonomous regions) in western China from 2009 to 2020,the index system of forestry ecological poverty alleviation is established by using principal component analysis (PCA) and entropy method. T he fixed effects regression model established through empirical research is used to study the impact of forestry ecological poverty alleviation on farmers' income. ⑶ Results——The regression results show that the coefficient of forestry ecological poverty alleviation is significant at 1% level, that is, forestry ecological poverty alleviation promotes the improvement of farmers' income level. When forestry ecological poverty alleviation changes by 1%,farmers' income will increase by 1.92%, and it has long-term effects. Third, the industrial effect of forestry ecological poverty alleviation has greater impact on farmers' income than the ecological effect and employment effect. The industrial effect is significantly positive at 1% level, while the ecological effect and employment effect are not significant. Fourth, since 2015, the intensity of forestry ecological poverty alleviation in China has been enhanced and the income effect has been significant. The analysis of the trend of forestry ecological poverty alleviation indexes shows that before 2015,forestry ecological poverty alleviation(average) fluctuated steadily at about 0.17.After 2015,the growth rate was more obvious, peaking at 0.25 in 2019.Taking 2015 as the dividing line, the panel data is divided into two groups. The regression of the two groups of data shows that the income effect from 2015 to 2020 was significant. Fifth, forestry industry upgrading has a significant positive moderating effect on the impact of forestry ecological poverty alleviation on farmers' income. The coefficient of forestry ecological poverty alleviation is significantly positive at 1% level, and the interaction term is significantly positive at 5% level. ⑷ Conclusions and Discussions——First, forestry ecological poverty alleviation should take into account the dual objectives of ecology and economy, and deal with the relationship between development and protection according to local conditions. It is necessary to implement ecological compensation, employment assistance and industrial drive, promote the rational utilization of forestry resources, and expand the income channels of farmers. Second, optimize the forestry industry structure, upgrading the industrial value chain, cultivate forestry products with high value-added forestry products and explore a new path for poverty alleviation through integrated development of forestry primary, secondary and tertiary industries to improve the effectiveness of forestry ecological poverty alleviation. Third, improve the ecological compensation mechanism, gradually expand its coverage and raise the compensation standards, and explore diversified compensation methods. Fourth, coordinate the relationship between “government dominance” and “market vitality”, he government should give full play to its public service function and improve its ability of ecological governance. At the same time, the vitality of efficient markets should be stimulated. [ABSTRACT FROM AUTHOR]
