摘要
为了解碳约束下生鲜农产品冷链物流发展效率,加速低碳冷链物流业的发展,文章利用超效率 SBM-DEA和 GML指数方法,测度中部六省 2011-2021 年在碳约束下生鲜农产品冷链物流静态效率值及动态变化趋势,选取年度效率值进一步研究生鲜农产品冷链物流发展的空间变化.研究表明:整体而言,中部六省生鲜农产品低碳物流发展效率值总体不高;时间维度上,中部六省生鲜农产品低碳物流发展效率值呈现缓慢波动上升趋势,且各省份间效率值差距较大,但差异逐年减小;空间维度上,生鲜农产品冷链物流发展高效率区域由东向西逐渐移动,最终呈现出各区域均衡发展的趋势.最后,从不同维度提出相关建议,以促进中部六省生鲜农产品冷链物流协调发展.
Abstract
To understand the efficiency of cold chain logistics development for fresh agricultural products under carbon constraints and accelerate the development of low-carbon cold chain logistics in-dustry,this article uses the super efficiency SBM-DEA and GML index methods to measure the static efficiency values and dynamic trends of fresh agricultural cold chain logistics in the six central prov-inces from 2011 to 2021 under carbon constraints.Finally,the annual efficiency values of the six cen-tral provinces are selected to further study the spatial changes in the development of fresh agricultural cold chain logistics in the six central provinces.Research shows that:(1)Overall,the overall devel-opment efficiency of low-carbon logistics for fresh agricultural products in the six central provinces is not high.(2)In terms of time dimension,the efficiency value of low-carbon logistics development for fresh agricultural products in the six central provinces shows a slow fluctuating upward trend,and there is a signifi-cant difference in efficiency values among provinces,but the difference is decreasing year by year.(3)In terms of spatial dimension,the high-efficiency areas for the development of fresh agricultural cold chain logis-tics gradually move from east to west,and ultimately show a trend of balanced development among various re-gions.Finally,relevant suggestions are proposed from different dimensions to promote the coordinated devel-opment of cold chain logistics for fresh agricultural products in the six central provinces.
