Determinants of the future level of use of electronic marketplaces: The case of Canadian firms

Based on the literature dealing with the diffusion of innovation and with information systems, and building on the emerging concepts in electronic commerce (e-commerce), this paper aims at assessing the influence of various factors on firms’ future level of use of electronic marketplaces (e-marketplaces). This theoretical model is tested on data collected from 1,200 senior managers in Canadian firms. Findings indicate that a firm’s past experience in e-commerce, as well as the factors relating to its business relationships ultimately affect its future use of e-marketplaces. Results of TOBIT regressions also show that the complexity of sophisticated e-commerce implementations is negatively correlated with the future level of use of e-marketplaces, and that consultants and other experts play an essential role in encouraging and facilitating the use of this new type of electronic platform. Finally, our survey data demonstrate that the relative influence of some determinants differs according to the firms’ size.

农产品电子商务网站的建设与研究

农产品电子商务是一个借助于网络平台新型的农产品销售模式。用户将自己的各类相关信息按照一定的格式输入到电子商务这个系统中,此系统就会协助完成合同的签订、分类、传递和款项收付等全套业务,为卖方以较高的价格出售农产品,买方以较低的价格购入原材料提供了一条非常好的途径,而且也减少了运输渠道所带来的额外消费。因此,农产品电子商务网站的发展对农业的发展和农民的收入的提高有着极大的意义。

基于时序特征和集成算法的用户购买预测

大数据时代,电商平台积累了大量用户在平台上的行为数据,比如浏览、点击、下单和加入购物车等等.如何使用机器学习算法去探索大数据背后的用户消费喜好和习惯成为了一个新的研究热点.本文主要在特征工程和模型搭建两个方面对用户购买预测的效果做出提高.通过深入理解电商业务知识,利用统计学知识,分别从用户、商品和评论数据等多个方面的数据构建了115个特征;在模型搭建方面,主要设计了一个两层融合模型,第一层采用了XGBoost、CatBoost和逻辑回归作为基分类器,从不同的角度考虑用户购买预测,第二层采用加权平均的方法对基类模型的预测结果进行融合,其权重由线性分类器学习生成.实验结果表明该融合模型的F1评分要高于个体分类器,并且多次实验证明,融合模型的稳定性也要比个体分类器好.

Trust fraud: A crucial challenge for China’s e-commerce market

Currently, China’s e-commerce market is growing at an unprecedented pace, however, it is faced with many challenges, among which the trust fraud problem is the biggest issue. In this article, we use Taobao as an example and conduct a thorough investigation of the trust fraud phenomenon in China’s e-commerce market. We present the development history of trust fraud, summarize its unique characteristics, and explore the reasons why so many sellers commit fraud. We further propose a dynamic time decay trust model that aims to deter trust fraud by raising its cost and promote the growth of small and medium-sized sellers. The model utilizes detailed seller ratings as the data source, and incorporates a transaction amount weight, a time decay coefficient, and three trust factors in the calculation of trust. We test the model on real transaction data from Taobao, and the experimental results verify its effectiveness. Our proposed trust model yields a practical approach to online trust management not only in the Taobao market but also for other e-commerce platforms.
