[Ecological benefits of transfer payment of natural forest protection projects and their impact mechanisms].

The policy of natural forest protection project (NFPP) is of great significance to the protection and restoration of natural forests. It remains unclear about how to play the role of NFPP transfer payment in forest ecological benefits. Based on panel data of "China Forestry Statistical Yearbook" from 2011 to 2017, we used forest management area and forest tending area as indicators to measure forest ecological benefits, and used spatial lag model and intermediary effect model to analyze the impacts of the transfer payment funds of NFPP on the forest ecological benefits in key state-owned forest areas. The results showed that forest ecological benefits in the key state-owned forest areas in the second phase of NFPP had improved year by year. There was a significant spatial spillover effect of forest ecological benefits of forestry bureaus. The transfer funds of NFPP had a significant positive effect on the ecological benefits of forest resources in key state-owned forest areas. There was a partial intermediary effect between the improvement of human capital and the establishment of first-line management and protection stations. The central government should increase investment in the transfer payment funds of NFPP. Forest administrations should increase the proportion of funds used in improving human capital and establishing first-line management and protection stations.
