The Impact of Forestry Industry Agglomeration on Forestry Economic Growth：An Empirical Analysis Based on 11 Provinces and Autonomous Region in Southern Collective Forest Areas

Based on the theoretical analysis of the impact of forestry industrial agglomeration on forestry economic growth,taking 11 provinces of southern collcetive forestry area as an example,this paper uses the long panel data from 1998 to 2018 to measure the level of forestry industrial agglomeration on 11 provinces in southern collective forestry area by using the location entropy index. Based on the Cobb-Douglas production function, after selecting the fixed-effects model, the feasible generalized least squares (FGLS) and utest test are used to empirically analyze the impact of forestry industry agglomeration on forestry economic growth. The research results show that: （1） there are spatial and temporal differences in the level of forestry industry agglomeration on 11 provinces in southern collective forest area; （2） there is an “inverted U-shaped” relationship between forestry industry agglomeration and forestry economic growth. Therefore, firstly, we should pay attention to the law of forestry industry agglomeration development and control it within a reasonable range; secondly, we should focus on improving the quality of forestry industry agglomeration and optimizing the industrial layout; finally, we should develop different and targeted industrial agglomeration development measures.
