基于改进引力模型的跨境电商综合实力评价体系研究--以浙江省为例

Research on Comprehensive Strength Evaluation System of Cross Border E-commerce Based on Improved Gravity Model:An Evidence from Zhejiang Province

我国跨境电商市场交易规模快速增长,跨境电子商务综合试验区的数量已达105个,基本覆盖了我国主要省市区。浙江省是全国唯一拥有5批跨境电商综试区的省份,且区域范围基本覆盖行政区域全境,因此,其跨境电商发展演化过程可以对其他地区有学习借鉴意义。本文以浙江省内各跨境电商综试区为例,基于改进引力模型构建综合实力评价体系,并对其所在城市之间的联系进行实证分析。实证分析表明:本文所改进的引力模型能够全面反映各跨境电商综试区城市综合实力、发展定位和评价体系。浙江省内各跨境电商综试区联系呈现“杭州、宁波为中心向外辐射”的特征。省内各综合实力发展程度可以被分为中心型、平衡型、成长型和薄弱型4种类型。在此基础上,文章为如何破除行政壁垒,深化城市间联系和融合,达到优化整体城市布局、实现协同发展目的提出了政策建议。

The transaction scale of China's cross-border e-commerce market is growing rapidly.The number of cross-border e-commerce comprehensive pilot zones has reached 105,basically covering major provinces and cities in China.Zhejiang Province is the only province in China with five batches of cross-border e-commerce comprehensive test zones,and the regional scope basically covers the whole administrative region.Therefore,the development and evolution process of cross-border e-commerce can be learned for other regions.Taking the cross-border e-commerce comprehensive pilot zones in Zhejiang Province as an example,the authors construct a comprehensive strength evaluation system based on the improved gravity model,and makes an empirical analysis on the relationship between cities.The empirical analysis shows that the improved gravity model can fully reflect the comprehensive strength,development orientation and evaluation system of cities in cross-border e-commerce comprehensive test areas.The connection of cross-border e-commerce comprehensive pilot zones in Zhejiang Province is characterized by"Hangzhou and Ningbo as the center and radiating outward".The development degree of comprehensive strength of various regions in the province can be divided into four types:central type,balanced type,growth type and weak type.On this basis,the authors put forward some policy suggestions on how to break down administrative barriers,deepen the connection and integration between cities,optimize the overall urban layout and achieve coordinated development.
