科技创新对珠江西岸物流产业效率的影响——基于超效率三阶段数据包络分析模型

Impact of Scientific and Technological Innovation on Logistics Industry Efficiency in the West Bank of the Pearl River:Based on Super-efficiency Three-stage DEA Model

鉴于关于科技创新对珠江西岸地区物流影响的计量和实证研究尚不足,对此,构建珠江西岸物流产业投入产出指标体系,运用超效率三阶段数据包络分析模型测度其2011—2020年剔除环境影响因素后的物流效率,并通过第二阶段随机前沿分析法分析科技创新相关因素对物流产业效率的影响。结果发现:珠江西岸各城市物流产业效率存在较大差异,总体物流综合技术效率不高,主要原因在于规模效率低,其中2015—2016年为综合技术效率的低位拐点;政府支持与信息服务投入对物流效率影响较大,环境变量显著影响物流效率。最后提出提高区域协同水平,发展以市场为主、政府为辅的物流业等建议,以促进珠江西岸物流业高质量发展。

In view of the lack of quantitative and empirical studies on the impact of scientific and technological innovation on logistics in the West Bank of the Pearl River,an input-output index system of logistics industry in the West Bank of the Pearl River is constructed,then the super-efficiency three-stage data envelopment analysis model is used to measure the logistics efficiency excluding environmental factors from 2011 to 2020,and the second stage stochastic frontier analysis is used to analyze the influence of related factors of scientific and technological innovation on the efficiency of logistics industry.The results show that there are great differences in logistics industry efficiency among cities on the West Bank of the Pearl River,and the overall logistics comprehensive technical efficiency is not high,which is mainly due to the low scale efficiency,especially there is a low turning point of comprehensive technical efficiency in 2005 and 2006;government support and information service input have a great impact on logistics efficiency,and environmental variables have a significant impact on logistics efficiency.Finally,suggestions are put forward to improve the high-quality development of the logistics industry in the in 2005 and 2006 of the Pearl River,such as improving the level of regional coordination,and developing a logistics industry dominated by the market and supplemented by the government.
