摘要
文章以宁波市为研究对象,构建宁波市区域物流与区域经济的评价指标体系,基于2010-2019年统计年鉴的数据,将数据进行描述性统计后,通过最大最小值标准化处理与熵值法权重构建宁波市区域物流与经济发展水平评价指数,通过ADF单位根检验筛选平稳的时间序列,利用格兰杰因果关系检验分析宁波市区域物流的发展水平与宁波市区域经济发展水平之间的相关性,从经济视角探究两者之间的互动关系。最后通过灰色关联度模型进一步计算宁波市区域物流与区域经济之间的影响程度。结果表明,区域物流投入、区域物流产出对总体经济规模、产业经济规模、区域贸易规模存在正向的影响作用,且区域物流产出与区域经济发展水平之间存在较高的关联度。
Taking Ningbo as the research object,this paper constructed the evaluation index system of Ningbo regional logistics and regional economy.Based on the data queried in the statistical yearbook from 2010 to 2019,after descriptive statistics of the data,this paper constructed the evaluation index of Ningbo regional logistics and economic development level through maximum and minimum standardized processing and entropy weight method.The ADF unit root test was used to screen the stable time series,and the Granger causality test was used to analyze the correlation between the development level of regional logistics in Ningbo and the development level of regional economy in Ningbo,so as to explore the interactive relationship between them from an economic perspective.Finally,the influence degree between regional logistics and regional economy in Ningbo was further calculated by grey correlation model.The results showed that regional logistics input and output had a positive impact on the overall economic scale,industrial economic scale and regional trade scale,and there was a high correlation between regional logistics output and regional economic development level.
