摘 要:根据2010~2019年中国31省市的面板数据,基于熵权赋值法和耦合协调度模型对中国物流业与信息业耦合协调度进行了评价。研究结果表明:时间维度下,中国物流业与信息业之间的耦合协调度稳步提高,2019年达0.6851,接近中级协调发展类;八大综合经济区视角下,东、北、南部沿海地区的耦合协调度最高,呈正向耦合,其余五大地区则均处于负向耦合阶段。其中大西南、长江中游地区的耦合协调度呈上升趋势,大西北、黄河中游地区的耦合协调度波动性明显,发展停滞;东北地区的耦合协调度则持续大幅下滑,呈现出明显的衰退趋势。

Abstract: According to the panel data of 31 provinces and cities in China from 2010 to 2019, based on entropy weight assignment method and coupling coordination degree model, the coupling coordination degree between logistics and information industry in China is evaluated. The research results show that under the time dimension, the degree of coupling coordination between the logistics industry and the information industry in China has been steadily improved, reaching 0.6851 in 2019, which is close to the intermediate level of coordinated development; from the perspective of the eight comprehensive economic zones, the coastal areas in the east, north and south have the highest degree of coupling coordination with positive coupling, while the other five regions are in the stage of negative coupling. The coupling coordination degree in the southwest and middle reaches of the Yangtze River is on the rise, while the coupling coordination degree in the northwest and middle reaches of the Yellow River fluctuates significantly and stagnates. The coupling coordination degree in northeast China continues to decline sharply, showing an obvious trend of decline.

物流业是国民经济发展的支柱产业。2019年全社会物流总额保持平穩增长,为298.0万亿元。按可比价格计算,同比增长5.9%,增速比上年同期回落0.5%。中国物流业发展呈趋稳趋缓的发展态势,正处于转型升级的重要关口。在信息化时代的大背景下,信息逐渐成为各行业生产要素配置的重要组成部分,也成为推动物流业转型升级的重要要素。同时,物流业是综合性极强的复合型产业,能通过产业关联性带动信息行业的发展。因此,研究物流业与信息业交互耦合现象,对于促进中国两产业协调发展有着重要的时代意义。
近年来,研究信息业与物流业协同发展的文献屡见不鲜。其中,对物流信息化的研究较为丰富,如楼旭明等(2020)指出国内物流……
