林业技术进步对林业产业结构升级影响的空间效应

Spatial Influence Effect of Forestry Technology Progress on the Upgrading of Forestry Industrial Structure

用DEA-Malmquist指数法和产业结构层次系数测度林业技术进步和林业产业结构升级水平,并检验林业产业结构升级的空间相关性,以及进行林业技术进步对林业产业结构升级影响的空间计量。结果表明:林业产业结构升级有明显的空间正相关关系,各区域存在高值集聚、低值集聚现象;林业技术进步对林业产业结构升级有显著的正向促进作用,区域空间影响效应表现为东部区域不显著(P>10%),中部区域负显著(P<10%),西部区域正显著(P<10%)。

DEA-Malmquist index method and the level coefficient of industrial structure were used to measure the level of forestry technology progress and forestry industrial structure upgrade. The spatial correlation test of the upgrading of forestry industrial structure was carried out. Then, the spatial measurement of the influence of forestry technology progress on the upgrading of forestry industrial structurewas analyzed. The results show that there is an obvious positive spatial correlation in the upgrading of forestry industrial structure. The phenomenon of high-value agglomeration and low-value agglomeration exists. National forestry technology progress has a significant positive promoting effect on the upgrading of forestry industrial structure. The regional spatial influence effect of forestry technology progress on the upgrading of forestry industrial structure is not significant in the eastern region(P>10%), negative in the central region(P<10%), and positive in the western region(P<10%).
