With the ever-increasing diversification of people’s interests and preferences,artwork has become one of the most popular commodities or investment goods in e-commerce,and it increasingly attracts the attention of the public.Currently,many real-world or virtual artworks can be found in e-commerce,and finding a means to recommend them to appropriate users has become a significant task to alleviate the heavy burden on artwork selection decisions by users.existing research mainly studies the problem of single-artwork recommendation while neglecting the more practical but more complex composite recommendation of artworks in e-commerce,which considerably influences the quality of experience of potential users,especially when they need to select a set of artworks instead of a single artwork.Inspired by this limitation,we put forward a novel composite recommendation approach to artworks by a user keyword-driven correlation graph search named ART_(com-rec).Through ART_(com-rec),the recommender system can output a set of artworks(e.g.,an artwork composite solution)in e-commerce by considering the keywords typed by a user to indicate his or her personalized preferences.Finally,we validate the feasibility of the ART_(com-rec) approach by a set of simulated experiments on a real-world PW dataset.

In the growing e-commerce industry,the problem of malicious business operations has become increasingly prominent,exposing many problems such as weak supervision of e-commerce platforms and no way for consumers to complain.In order to solve the problems of counterfeit and shoddy products on e-commerce platforms and promote the sustainable development of the e-commerce industry in China,this paper constructs a three-party evolutionary game model of e-commerce platforms,merchants,and consumers,investigates the influence of each influencing factor on each party’s strategy choice,and provides targeted suggestions to e-commerce platforms based on relevant factors.Finally,the impact of several important parameters on the equilibrium solution is discussed through sensitivity analysis.The results show that:1)the smaller the cost difference between active and negative regulation,the more the e-commerce platform tends to active regulation strategy,but increasing fines for dishonest merchants and consumer complaints have little impact on the e-commerce platform;2)increasing consumer compensation,creating an honest business environment,and reducing the cost of honest business all help companies tend to operate in good faith;3)the only factor that affects the tendency of consumer complaint strategies is the cost of complaints.The loss suffered by silence and the compensation given to consumers have little effect on consumers’tendency to complain strategy.The results can provide theoretical guidance for participants to make useful strategic decisions in the e-commerce market.

With the rapid development of information technology and fast growth of Internet users,e-commerce nowadays is facing complex business environment and accumulating large-volume and highdimensional data.This brings two challenges for demand forecasting.First,e-merchants need to find appropriate approaches to leverage the large amount of data and extract forecast features to capture various factors affecting the demand.Second,they need to efficiently identify the most important features to improve the forecast accuracy and better understand the key drivers for demand changes.To solve these challenges,this study conducts a multi-dimensional feature engineering by constructing five feature categories including historical demand,price,page view,reviews,and competition for e-commerce demand forecasting on item-level.We then propose a two-stage random forest-based feature selection algorithm to effectively identify the important features from the high-dimensional feature set and avoid overfittlng.We test our proposed algorithm with a large-scale dataset from the largest e-commerce platform in China.The numerical results from 21,111 items and 109 million sales observations show that our proposed random forest-based forecasting framework with a two-stage feature selection algorithm delivers 11.58%,5.81%and 3.68%forecast accuracy improvement,compared with the Autoregressive Integrated Moving Average(ARIMA),Random Forecast,and Random Forecast with one-stage feature selection approach,respectively,which are widely used in literature and industry.This study provides a useful tool for the practitioners to forecast demands and sheds lights on the B2C e-commerce operations management.

Journal of Social Computing 2024年第1期5卷 46-57页

作者： Yu Chen Luwei Xiang Hu Yang School of Public Finance and Taxation Central University of Finance and EconomicsBeijing 100008China School of Management and economics The Chinese University of Hong KongShenzhen 518172China School of Information Central University of Finance and EconomicsBeijing 100008China

The value-added tax(VAT)in China is levied and allocated based on the origin principle.Under the background of the increasing substitution of online retail for traditional offline retail,this mechanism will exacerbate the disparity of regional tax revenue,and intensify tax competition among local governments.Therefore,reconsidering the allocation mechanism of value-added tax in China can be an important policy decision,and it is influenced by various economic and social factors.Firstly,we utilize large-scale retail transaction data from an e-commerce platform to measure regional disparities in retail and consumption among different regions and then reveals present tax policy results in revenue imbalance in different regions.Secondly,we establish a model based on game theory to illustrate how the origin principle leads to fierce tax competition among regions.Furthermore,by establishing and solving tax allocation models between local governments and the central government,this study simulates and calculates the degree of revenue imbalance under different scenarios and attempts to propose policy measures.The results indicate that implementing the destination principle will reduce regional tax imbalances.Moreover,adjusting the allocation ratio between the central government and local governments based on city levels is advantageous for further reducing regional tax revenue disparities.

作者： Ali Alkhalifah Fadwa Alorini Reef Alturki Department of Information Technology College of ComputerQassim UniversityBuraydah52211Saudi Arabia

The revolution of technology and the rapid evolution of the digital world had a signiﬁcant effect on the development and expansion of e-commerce.Last mile delivery,for which different app-based delivery services have recently emerged,is a new area of research that is not thoroughly addressed.Delivery ser-vice is one of the supporting platforms of e-commerce.One of the delivery issues is that many customers experience difﬁculties in communicating and coordinating with the logistics companies responsible for the delivery service.This challenge is emphasized in this study which introduces a new system to facilitate communica-tion and coordination between customers and logistics companies by using one identity and one interface.This paper is a programming-based study,as the pro-posed system evaluates a website to serve logistics companies as well as designs an application(app)to serve the customers of logistics companies.Swift,a power-ful open-source and object-oriented programming language,and the mark-up language(HTML)were used to build the last mile delivery system.In addition,Firebase,a cloud-hosted real-time database built on Google infrastructure,were used to develop the system.By increasing the level of customer satisfaction and reducing delivery failure rates,this system will eventually increase the prosperity of e-commerce.

China & World economy 2023年第5期31卷 61-86页

作者： Zhou Jiang Maoxia Zeng Mingming Shi Institute of Western China economic Research Southwestern University of Finance and EconomicsChina School of Business Renmin University of ChinaChina

Consumption inequality may impede economic development and hinder the achievement of common prosperity.Using three waves of the China Family Panel Studies from 2014 to 2018,this paper investigated the impact of e-commerce on consumption inequality,as measured by the Kakwani index.The results indicate that e-commerce can reduce household consumption inequality.A mechanism analysis shows that e-commerce can narrow household income inequality,increase the purchasing power of low-income households,and promote the consumption of households with limited access to ofline markets,thereby reducing the consumption gap.A heterogeneity analysis suggests that the positive role of e-commerce in reducing consumption inequality can be more significant among vulnerable households,such as households with elderly members and less-educated households.e-commerce can have varying impacts on consumption inequality across different subcategories of household expenditure,with the greatest impact seen in entertainment and education expenditure.These findings provide new evidence for the role of e-commerce in reducing consumption inequality in the digital economy,and the implications of this are discussed.

Considering diseconomies of scale and network externalities in the e-commerce supply chain(eCSC),we construct an e-platform-led benchmark model and derive the optimal decisions.Then,the model is extended by endogenizing the impact of service level on network externalities.Considering service investment that includes fixed and variable investments,the model is further extended.Comparing the extended models with the benchmark model,we found the following conclusions.Although the e-platform dominates the eCSC,its profit is lower than the manufacturer.The corporate profits,service level,and price increase with network externalities.Increases in diseconomies of scale decrease the corporate profits and service level,but increase the price.A high-quality service combined with network externalities can achieve synergy and improve the e-platform’s economies of scale,further generating a higher profit.Improving network externalities promotes the fair profit distributionin eCSC and achieves stable development.

Coopetition between B2C e-commerce Companies:Price Competition and Logistics Service Cooperation

Journal of Systems Science and Systems engineering 2020年第6期29卷 730-752页

作者： Weixiang Huang Wenhui Zhou Feng Luo School of Business Administration South China University of TechnologyGuangzhou 510640China School of e-commerce and Logistics Beijing Technology and Business UniversityBeijing 100048China

This paper studies the impact of logistics cooperation in two competing companies,one of which is equipped with a self-run logistics system while the other is not.The latter outsources logistics services to a third-party logistics company before logistics cooperation,or to its competitor after logistics cooperation with the client's service quality being in proportion to and no greater than the service provider's service quality.We find that when the service provider is a price taker,logistics cooperation is beneficial to both firms only when the service quality after logistics cooperation is moderate.Interestingly,under some circumstances,the client's profit increases even when its service quality decreases after logistics cooperation because logistics cooperation eases the price competition.We also find that all-win situations in which logistics cooperation increases the firms7 profit,consumer surplus and social welfare can be achieved.Finally,when the service price can be chosen by the service provider,we propose a negotiation process in which agreement on logistics cooperation can be reached;when the firm can invest in service quality,logistics cooperation may lower the equilibrium investment level.
