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. 展开更多

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. 展开更多

Crossing border e‐commerce develops rapidly because of e‐commerce development.There are three typical modes of crossing border e‐commerce,and they are B2B(business to business),B2C(business to customer),and C2C(customer to customer).With the development of social network,a new mode called C2C cross‐border e‐commerce by SC(social commerce)is occurring.This new kind of e‐commerce has several advantages,like high trust between seller and customer and personalized consumption for customers.But there are still some problems of C2C cross‐border e‐commerce by SC,which are tax evasion and no rule to regulate.To solve these problems,several measures should be taken into account.In the area of Customs Law,it should refine the standard of luggage and post package taxation.The Custom should strengthen supervision for international post package.To deal with the problem that there is no law to regulate C2C cross‐border e‐commerce by SC,Contract Law is suitable before the E‐commerce Law enacts. 展开更多

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. 展开更多

Cross border trade is a source of livelihood for many poor people, especially women. However, few studies examined challenges facing cross border traders and future business prospects.The aim of this paper is to examine the challenges that face Zimbabwean cross border traders in South Africa. The paper goes further to review existing literature as well as empirical studies in order to identify the major challenges that face Zimbabwean cross border traders. Among the challenges noted are crime, harassment due to xenophobia, traders are often stigmatized as "prostitutes" or "smugglers", accommodation problems, extortion and bribery by the South African Police and municipal police officials, delays at the border post during peak periods and banks that close early and also do not operate on Sundays. The Zimbabwean Cross Border Traders Association should build office in Musina and Johannesburg so that members can easily consult with the association in times of problems and also help with marketing information like distribution of brochures showcasing Zimbabwean products sold by cross border traders and also organize fairs where Zimbabwean traders can display their products. Furthermore cases of harassment by police officials should be investigated and dealt with. Banks that do have branches at the border posts are also urged to provide 24 hour service to cross border traders. 展开更多

Alice Ridout and Susan Watkins offers a best perspective in their book Doris Lessing: Border Crossings, to contemplate Lessing’s writing. In her 57-year publishing career, Lessing always crosses the borders: as a feminist or anti-feminist, as a science fiction writer or a realist who lost her way, as a Marxist or a reactionary, as a British writer or a postcolonial one. Lessing’s border-crossing not only lies in her different genres of writing or in different novels, but even in a single comparatively traditional novel. The Summer Before the Dark is a representative work of Lessing’s women portrayal transition from focusing on their outside world exploration to on their inner world seeking. This essay tries to look at the content and form of the novel, and to illustrate that Lessing’s border-crossing is also fulfilled in one single novel. She successfully crosses the border of convention and innovation: conventional in content, while innovative in form. 展开更多

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.

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. 展开更多
