林业产业生态安全效率的SBM-Malmquist测度与时空特征分析

SBM-Malmquist Measurement and Spatial-temporal Characteristics Analysis of Eco-security Efficiency of Forestry Industry

摘要:

现有林业生态安全研究存在“就生态论生态”,未考虑引起生态安全的产业因素等问题。站在林业生态与产业共生的视角对林业产业生态安全效率进行测度是一个新的探索。基于SBM-Malmquist模型对2005年-2014年间全国31个省份的林业产业生态安全效率进行了空间和时间维度的测度。研究表明：林业产业的技术效率偏低、发展过于依赖规模的粗放型扩张；单靠技术效率的提升已不能解决林业生态安全发展中遇到的问题,技术进步指数偏低成为制约我国林业产业与林业生态协调发展的关键；不同省份林业产业生态安全效率发展不平衡且各有侧重,对效率安全区、技术效率主导的效率双高区、规模效率主导的低水平发展区和分解效率双低区等产业政策调整的侧重点差异较大。

Abstract:

The existing research on forestry ecological security has some problems, such as "ecology on the basis of ecology", not considering the industrial factors causing ecological security. It is a new exploration to measure the ecological security efficiency of forestry industry from the perspective of forestry ecology and industry symbiosis. Based on SBM-Malmquist model, the spatial and temporal dimensions of ecological security efficiency of forestry industry in 31 provinces of China from 2005 to 2014 were measured. The research shows that the technological efficiency of forestry industry is low and the development depends too much on the extensive expansion of scale; the improvement of technological efficiency alone cannot solve the problems encountered in the development of forestry ecological security, and the low index of technological progress has become the key to restrict the coordinated development of forestry industry and Forestry ecology in China; the development of forestry industry ecological security efficiency in different provinces is unbalanced and has its own emphasis. There are great differences in the emphasis of industrial policy adjustment, such as efficiency safety zone, technology efficiency-led efficiency double-high zone, scale efficiency-led low-level development zone and decomposition efficiency double-low zone.
