科技创新对珠江西岸物流产业效率影响分析——基于超效率三阶段DEA模型

Analysis of the impact of technological innovation on the efficiency of the logistics industry on the west bank of the Pearl River ——Based on the super-efficiency three-stage DEA model

摘要:

本文通过构建珠江西岸物流产业效率的投入产出指标体系，运用超效率三阶段DEA模型对2010-2019年珠江西岸的剔除环境影响因素后的物流效率进行了测度，在此基础上利用物流产业相关科技创新数据，运用面板回归模型分析科技创新对珠江西岸物流产业效率的影响。研究发现，珠江西岸各城市的物流产业效率存在较大的差异；物流综合技术效率不高主要是规模效率低造成的，规模效率仍有较大的提升空间；从环境因素来看，政府支持与信息服务投入对珠江西岸物流效率的影响较大；基础物流环节的科技创新未发挥对物流效率的促进作用，不同城市的科技创新效应存在差异。最后，基于珠江西岸的实际情况以及实证结果的分析提出：提高区域协同水平，推进珠江西岸物流一体化发展；加大信息服务业的投入，提高珠江西岸物流业信息化水平；发展以市场为主、政府为辅的物流业；有选择地加大物流业的科技创新要素投入等四点物流发展建议。

Abstract:

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. 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 in 2005 and 2006 there is a low turning point of comprehensive technical efficiency; 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 west bank 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.
