We design a cloud computing service supply chain with a monopoly application infrastructure provider (AIP) and multiple competing application service providers (ASPs) under asymmetric information. We use Bertrand competition to characterize the competitive relationship between ASPs. A service level agreement (SLA) serves as the foundation for the expected level of ASPs' services. The service system of ASPs is modeled as an M/M/1 queueing system while the effects of congestion are considered. We study the problem how to coordinate the cloud computing service supply chain with revenue-sharing contract under asymmetric information ,and propose a new model relevantly. In our model ,the AIP as the leader has the decision-making right for wholesale price and revenue-sharing proportion ,while ASPs as the followers have just the right to conceal the information on marginal cost and determine the ordering computing capacity . We discuss the AIP's optimal revenue sharing strategy in case ASPs conceal the unit application service cost ,with a comparative analysis made under symmetrical information at the same time. A numerical simulation is done and the computing results show that the AIP 's optimal revenue-sharing strategy to spur ASP swill pay a price for the anonymity and unobservability of ASPs' private information and reduce his/her profit ,while ASPs can gain from that.

This paper builds a two-stage game supply chain model where a manufacturer and a retailer transact via a wholesale price contract. Based on a standard wholesale price contract, the model captures the manufacturer's product recall decisions under product liability regulations. With the subgame perfect equilibrium, the comparative statics results show that (1) the manufacturer's product recall decision is independent of product liability; (2) except that in response to a raised product recall cost, the manufacturer's product recall decision and supply chain members' financial performance change harmoniously, the manufacturer's product recall decisions are in conflict with supply chain members' financial performance in response to changes in consumer's harm and product quality; (3) whether the manufacturer's wholesale price increases in product quality (product recall cost) depends on the relative size of product liability and consumer's harm.

This paper presents a conceptual research of exploring the decision-making behaviors of supply chain financing (SCF) service providers (i.e. banks) in small and medium sized enterprise (SME) segments via electronic platforms (E-platforms). Specifically, this paper aims to investigate on the risk-taking behavior (i.e. offering the SCF services or not) and pricing behaviors (i.e. setting interest rate) of banks by leveraging different types of supply chain (SC) transaction information collected in the third-party E-platforms. As a result, some critical types of SC transaction information could be identified to be needed in the collaboration between banks and third-party E-platform service providers and facilitate the decision-making in SCF loans for banks. As such, some practical guidelines will be provided to help banks to select qualified SCF clients in the SME segments and make the SCF business both profitable and sustainable based on efficient decision-making practices. In addition, credit rationing theory and transaction cost theory will be deployed to help discern the problems pertinent to information asymmetry between banks and SMEs.

With the rapid development of the national economy and the speeding up of urbanization, the rail transport is gradually becoming the main way of the urban public transportation. The rail transit, as a kind of large capacity, high speed, safety and punctual transportation, not only improves the accessibility of the urban traffic, but also raises the new commercial circle. It brings a huge impact to the development of urban commercial space. In recent years, with the rapid development of Zhuhai, the government has started the constructions of the rail system and the north station TOD project in order to alleviate the traffic congestion in the downtown of Zhuhai. Based on the north station TOD projects, the relationship between the rail transit and the urban commercial space had been analyzed. The rail transit impact on development of commercial space had been studied.

In many applications such as dynamic social network and customer behavioral analysis, the data intrinsically have many dimensions and can be naturally represented as high-order tensors. In this study, a SVM ensemble learning method is proposed for classification using tensor data. The method is used in identifying cross selling opportunities to recommend personalized products and services to customers. Two real-world databases are used to evaluate the performance of the method. Computational results show that the SVM ensemble learning method has good performance on these databases.

Taking the factor of customer switching into count, we analyze duopoly models in which both start-ups and established firms consider the competitive investment in R&D when they enter the new market. Firms make a decision on investment will influence the customer switching. The firms with investment may attract new customers from other firms which does not invest and then maintain more market share. In our models, we assume the two kinds of firms have different investment objectives: established firms make the investment consideration to maximize the expected profit, whereas start-ups just try to maximize the probability of survival (Robert Swinney, 2011). Considering the customer switching, we work out four kinds of different results in this game. Finally, numerical examples are used to illustrate the models.

This paper finds that the single maximum daily AAR and CAR are greater during the directional add-issuance declaration which large shareholders subscribe or replace new shares with their assets than not by event study. So the signal effect of behavior of large shareholders in the directional add-issuance exists in the listed companies in China. But the factor analysis shows that the directional add-issuance that the large shareholders participate cannot bring long-term performance to improve or enhance, and the cumulative score is negative and declining. Moreover, the large shareholders participate in the directional add-issuance though they that the performance of the company is a substantial decline before directional add-issuance. In this paper, the subscription or replacement of large shareholders is intended to changing market expectations and valuation, and attract external market and small-medium investors to subscribe which is the abuse of the signal effect of the directional add-issuance.
