基于面板数据变系数模型的信息化与物流关系研究

Study on the Relationship between Informatization and Logistics Based on Varying Coefficient Models of Panel Data

基于面板数据变系数模型,采用2002-2010年间中国31个省份的面板数据,分析了信息化与物流的关系。结果显示:信息化对物流具有显著贡献,推进信息化对物流发展水平的提高具有积极意义。不同地区信息化对物流的贡献相差不大,可能的原因是多方面的:信息化对物流的推动作用本身与地区关系不大;信息化水平和物流发展水平均以东部地区最高、西部地区最低,信息化水平超前于物流发展水平。

Based on varying coefficient models of panel data,panel data of 31 provinces in China from year 2002 to 2010 were used to analyze the relationship between informatization and logistics.Results indicate that informatization makes a great contribution to logistics.Therefore promoting the informatization level is positive to the improvement of logistics.In addition,there is no significant difference among the contribution of informatization to logistics in different regions.Possible reasons are many-sided as follows.Firstly,the promoting role of informatization to logistics itself is not so relative to the region.Secondly,the informatization level and the logistics level are both the highest in the East China and the lowest in the West China.Finally,the informatization level runs ahead of the logistics level.
