摘 要:林业既是国民经济的重要生产部门,也是生态文明建设的重点领域,提高林业生产技术效率是高效利用林业资源的关键环节。本文采用超效率SBM模型测算了中国30个省(直辖市、自治区)2004—2018年的林业生产技术效率,在考虑空间因素的前提下,基于空间条件β收敛模型对其收敛趋势及时空分异特征展开分析。研究发现:(1)从林业生产技术效率的测度结果来看,全国层面林业生产技术效率总体水平不高,存在较大提升空间;林区层面由高到低依次为西南、南方、东北、华北、西北林区;省份之间差距同样明显,但同一林区内省份间差距小于不同林区的省份间差距。(2)就林业生产技术效率的收敛性而言,我国林业生产技术效率具有显著的空间条件β收敛趋势,且空间因素的纳入使得收敛周期缩短了约4年。林业对外开放程度、林业收入水平和林业产业结构对林业生产技术效率向高值收敛具有促进作用,而技术市场环境对其具有抑制作用,地区经济发展水平、林业人力资本水平和自然环境条件则影响不显著。(3)就林业生产技术效率收敛性的分异特征而言,空间上,五大林区均存在"俱乐部收敛"现象,且收敛率普遍高于全国平均水平,其中华北林区收敛率最高,东北、西南、西北林区次之,南方林区最低;时间上,2012—2018年收敛率高于2004—2011年,地区经济发展水平、林业对外开放程度等因素对林业生产技术效率的作用方向或力度在前后两个时期均有明显差异。为此,本文建议进一步完善林业体制机制,明确区域定位,因地制宜制定林业发展措施。Forestry is not only an important production sector of the national economy,but also a key area of ecological civilization construction.Improving the production technology efficiency(forestry PTE)is a key link in the efficient use of forest resources.In this article,the superefficiency slacks-based measure(SBM)model was used to calculate the forestry PTE of 30 provinces(municipalities,autonomous regions)in China from 2004 to 2018.Considering spatial factors,the convergence trend and spatial-temporal differentiation characteristics were developed based on the spatial conditionalβconvergence model.The study found that:(1)The overall level of forestry PTE at the national level was not high,and there was a large room for improvement.The forestry PTE at the major forest region level ranks from high to low in southwest,south,northeast,North China,and northwest forest region.The gap between the provinces was equally obvious.But the gap between provinces in the same forest regions is smaller than the gap between provinces in different forest regions.(2)At the national level,forestry PTE showed a significant spatial conditionalβconvergence trend,and the inclusion of spatial factors shortens the convergence period by about 4 years.The degree of forestry opening up,the level of forestry income,and the structure of forestry industry were positively correlated with the convergence to high values,while the technological market environment had a restraining effect.The level of regional economic development,the level of forestry human capital,and the natural environment had insignificant impacts.(3)From the perspective of forest regions,the five major forest regions showed a“club convergence”phenomenon,and the convergence rate was generally higher than the national average.The North China forest region had the highest convergence rate,followed by the northeast,southwest,and northwest forest regions,and the southern forest region have the lowest convergence rate.In terms of time periods,the convergence rate from 2012 to 201
