农林废弃物基质化产业联动模式:运行绩效、空间异质性及区域协同演化

CROP STRAW SUBSTRATE INDUSTRIAL LINKAGE MODE:RUNNING PERFORMANCE,SPATIAL HETEROGENEITY AND REGIONAL SYNERGY EVOLUTION

针对农林废弃物焚烧现象,作者采用微观数据调研与DEA—HR两步法模型等方法,对农林废弃物基质化产业联动模式的运行绩效、空间异质性及区域协同演化趋势进行了深入研究。实验结果表明:当前我国农林废弃物基质化产业联动模式的运行绩效仅为0.455,纯技术效率为0.649,规模效率为0.701,尚存在较大的提升空间,而规模效率偏低成为影响该模式运行绩效的主要因素。此外,农林废弃物基质化产业联动模式的运行绩效存在较大的空间异质性,且区域产业发展协调性较好,达到0.844,但其区域协同演化的有效性较差,仅为0.445,其中仅有"东南地区——长江中下游地区"、"长江中下游地区——华北地区"之间处于"协调且一般有效"状态,其他区域之间均为"协调且无效"状态,这与基质化产业在全国的低水平快速发展具有直接关系。

Aiming at the crop straw burning phenomenon,this paper studied on the operational performance,spa tial heterogeneity,and regional synergy evolution trend of the crop straw substrate industrial linkage model,using the methods of the microscopic data and DEA-HR two-step model.The results showed that the matrix of crop straw industrial linkage mode of operation performance was only 0.455,the pure technical efficiency was 0.649,the scale efficiency was 0.701,which was the main factor influencing the performance of the model.In addition,the operation performance had large space heterogeneity,and the regional industry development was 0.844,but the effectiveness of the regional synergy evolution was only 0.445.It was the status of 'coordination and general effective' insoutheast region-the Yangtze Rivers middle and lower reaches and the Yangtze Rivers middle and lower reaches-north China,but the other areas showed the 'coordination and invalid' status.
