Performance evaluation model of cross border e-commerce supply chain based on LMBP feedback neural network

In recent years,with the support of national policies,Cross Border E-Commerce(CBEC)has developed rapidly.This business model not only brings significant benefits to the national economy,but also has many unique challenges,especially at the level of supply chain management.Therefore,to enable CBEC enterprises to develop sustainable supply chain,this study discusses the performance evaluation model of supply chain and proposes a CBEC Supply Chain Performance Evaluation Model(CBECSC-EM)based on the Levenberg–Marquardt Backpropagation(LMBP)algorithm.This experiment constructs performance evaluation indicators for the supply chain of CBEC enterprises.On this basis,the LMBP algorithm is introduced,and improved in the experiment to make the overall performance of the evaluation model more scientific and reasonable.In the verification set,the maximum F1 values of LMBP,DEA,SBM,and BP are 98.46%,93.78%,87.29%,and 78.95%,respectively.The MAPE value of LMBP model is 0.102%,which is lower than the other three methods(0.282%,0.343%,and 0.385%)selected in the experiment.The maximum standard deviation rates of importance and operability of the evaluation indexes are 0.1346 and 0.1405,respectively,and there is a significant consistency between the expert scores.Therefore,the LMBP algorithm has broad application prospects in supply chain performance evaluation of CBEC enterprises.

China’s Cross-Border E-Commerce: Evolution Pattern and Influencing Factors

In recent years,while the traditional trade sectors have been shrinking,China’s cross-border e-commerce has undergone rapid development and has become a new driver of its international trade.Based on analysis of the evolution pattern of China’s cross-border e-commerce,this paper uses a revised gravity model to test empirically the driving factors and the resistance factors in the development of the country’s cross-border e-commerce.The results show that the total GDP,per capita disposable income of urban residents,total imports and exports,and the scale of the online shopping market have a positive relationship with cross-border e-commerce transactions,which are conducive to the development of cross-border e-commerce,while logistics costs inhibit the development of cross-border e-commerce.Accordingly,the paper puts forward several policy recommendations.

Crossing Borders: Negotiation of Dual Cultural Identity of Chinese American in Pangs of Love

David Wong Louie demonstrates the emotional pangs between the immigrant parent Mrs. Pang and her Americanized children in Pangs of Love. Through examining the source of the pangs, this paper argues that characters'pangs mainly stem from confrontations between their different cultural identities. Focusing on the way of dealing with conflicts of cultural identities in contemporary Chinese American families, this paper illuminates that Chinese Americans need to cross cultural borders and negotiate cultural identity between Chinese and American cultures under the circumstance of globalization.

Spatio-Temporal Dynamic of Land Use in the Dja-Odzala-MinkébéLandscape between Cameroon, Congo and Gabon: Influence on the Evolution of Forest Cover in a Context of Cross-Border Cooperation

This study is being carried out in the cross-border area of the tri-national Dja-Odzala-Minkébé (TRIDOM), subject of a cooperation agreement between Cameroon, Congo and Gabon in 2005. The purpose of this study is to analyze the dynamics of changes in land use in the context of cross-border cooperation. Geographic information systems and remote sensing were used to produce the various land use maps. For this purpose, the MERIS satellite images for the periods 1992, 2005 and 2018 were used. The exploration of the different images and the field visits made it possible to identify the following six land use classes: dense forests, degraded/deforested forests, savannas, swamp forests, buildings and bare soils, water surfaces. It emerges that the TRIDOM landscape is mainly occupied by dense forests which represent 97.02%, 96.72% and 96.52% respectively in 1992, 2005 and 2018. Then, degraded/deforested forests and savannas which would correspond to cultivation areas and fallow land only represent respectively 1.06% and 0.68% of the landscape in 1992. This proportion in 2005 is respectively 1.22% and 0.77%, whereas in 2018, it is respectively 1.36% and 0.81% of the massif. The landscape of TRIDOM has not experienced any significant land use change during the period after the signing of the cooperation agreement. Historical rates of deforestation are low during the period under study. They are estimated at 0.042% and 0.030% respectively for the period 1992-2005 and the period 2005-2018. These low rates of deforestation seem to be due to the measures taken to secure and sustainably manage the massif taken by the three countries, the low population density in this area and the still difficult level of accessibility of a large part of the massif.

On the Cross-border E-commerce Development Strategy in the Context of the Belt and Road Initiative

As the "Internet +" action plan proceeds, e-commerce further integrates traditional sectors and increasingly promotes development. In the context of the Belt and Road Initiative, Chinese cross-border e-commerce, through channel expansion and market share increase, is taking the lead in trade and investment development, and facilitating labor division & coordination, resource & product sharing, as well as opening new markets. To promote the long-term economic development of countries along the Belt and Road, a series of development strategies have been designed, which concern constructing an "online silk road" for cross-border e-commerce, building new trade passages and bridges, innovating traditional trade models, and gathering a trade development momentum.

Border Crossing in English——An Analysis of A College's Webpage

Border crossing in English, as a phenomenon in post-industrialized society, refers to forms of English in one situation are crossing borders into other ones. The originally formal institutional discourse in the written form can cross into the fields of advertising, informal, and spoken form. Informalisation and marketisation are the two distinct trends of border crossing. Institutions of higher education need to adjust their discourse to suit the development of the commercialized society.

中蒙农牧业跨境供应链协作理论框架及实现路径

中蒙农畜产品跨境贸易是中蒙跨境贸易的重要组成部分,须以中蒙农牧业跨境供应链为载体,通过供应链上各参与主体的充分协作,提高中蒙农畜产品跨境贸易的效率和质量。结合供应链协作理论以及中蒙农畜产品跨境贸易的特点,围绕中蒙农牧业跨境供应链协作目标、基础条件、协作机制以及协作模式,构建中蒙农牧业跨境供应链协作三角形理论分析框架。中蒙农牧业跨境供应链协作基础条件是两国农牧业跨境供应链协作的前提,协作机制解决两国农牧业跨境供应链协作的内在作用机理,协作模式解决两国农牧业跨境供应链如何协作,三者共同服务于协作目标,形成相互制约、相互影响、互促共融的完整理论框架。目前,中蒙农牧业跨境供应链协作存在着跨境贸易供需不足、渠道单一、政策障碍、市场主体运营不规范、信息不对称和融资障碍以及流通网络不健全等问题。中蒙农牧业跨境供应链协作要适度扩大农畜产品贸易的种类和规模,重视边民互市贸易,扩大边民互市贸易规模,加大草原保护及养殖技术创新力度、提高优质畜产品供给能力,加强农畜产品跨境电商合作、积极满足中蒙俄畜产品跨境贸易,优化贸易政策,制定统一的农畜产品标准和认证机制,重视品牌化战略、实现中蒙农牧业跨境供应链的价值提升,完善中蒙农牧业跨境物流通道和物流网络以及培育大型物流服务企业,构建中蒙农牧业跨境供应链信息平台等。

多情景模拟下的跨境铁路运输时效研究——以中老铁路为例

跨境铁路运输是中国与周边国家陆路联通的重要环节。跨境铁路运输时效既受线路畅通情况、基础设施技术等级等“硬联通”因素的制约,也受到海关条例、口岸畅通水平等“软联通”因素的影响。因此,跨境铁路运输时效研究应充分考虑不同情景,以期更科学地模拟运输时长的变化机理。本文以中老铁路(中国昆明−老挝万象,简称中老铁路)为例,在梳理中老铁路沿线地区社会经济概况及基础设施发展水平的基础上,考虑不同运营速度、通关时间、铁轨换装、多式联运等因素,构建了长途跨境运输时间的计算模型,采用多情景模拟方法,解析了中老铁路运的优势距离及客货运时效变化。研究表明:①中老铁路有助于沿线跨境运输时间显著减少。相比公路运输,客货运时间优势均超过20%;②通关时间是影响跨境铁路运输的关键要素之一,占运输总时长的20%~60%;③铁海联运是中老铁路运输进一步提升运输效率的途径,能有效缩短老挝至日本的总运输时间。

Crossing Cultural Borders

THIRTY-year-old Hong Jun, a Chinese Muslim from Yinchuan. capital city of west China＇s Ningxia Hui Autonomous Region, could not have imagined that his religious heritage and Arabic language skills would lead him to travel across the Arab world and even to estab- lish his own company. ＂I always saw studying Arabic as a means of communication, a way to build relation- ships, but never as a profession,＂ he said.

“内外兼修”企业社交媒体使用对突破式创新的驱动机制研究

数字化时代社交媒体蓬勃发展,为企业突破式创新带来了机遇。现实中,如何运用社交媒体实现突破式创新是企业面临的重要问题。结合组织学习理论、社会资本理论,从内外部视角探索两种社交媒体可供性对企业突破式创新的差异化作用机制。结果显示,内部整合导向的社交媒体使用通过组织忘却学习促进突破式创新,外部营销导向的社交媒体使用通过加深跨界用户嵌入促进突破式创新。此外,双元战略导向在两条路径上分别发挥调节作用。创业导向水平越高,内部整合导向的社交媒体使用对组织忘却学习的促进作用越显著;市场导向水平越高,外部营销导向的社交媒体使用对跨界用户嵌入的推动作用越显著。结论有助于丰富社交媒体与突破式创新相关研究,为企业应用社交媒体技术实现突破式创新提供启示。

跨境电商改革与出口企业数字技术创新——基于跨境电子商务综合试验区的准自然实验

跨境电子商务综合试验区建设是我国积极推进制度型开放的重要举措,税费优惠和管理服务完善等跨境电商改革不仅能够激励外贸增长,还会对出口企业产生成本降低效应、人力资本提升效应和内部治理优化效应等积极影响,从而促进出口企业的数字技术创新。将跨境电子商务综合试验区建设作为一项准自然实验,采用沪深A股出口企业2007—2020年的数据,运用多期双重差分模型分析发现:跨境电子商务综合试验区建设(跨境电商改革)显著促进了试验区出口企业的数字技术发明专利增长,跨境电商改革可以通过降低融资成本和经营成本、提高技术人员占比和高学历人才占比、提升公司治理水平和内部控制质量等路径促进出口企业的数字技术创新,跨境电商改革对融资约束程度较高、地区人力资源丰富、ESG表现较差、环境不确定性较强的出口企业具有更为显著的数字技术创新促进作用。应持续推进和不断深化跨境电商改革,并充分发挥制度型开放对企业创新发展的激励作用。
