Previous research indicates that information technology promotes innovation in general. The mechanisms of how information technology, such as e-commerce, can promote corporate innovation have not yet been fully recognized. The empirical results show that e-commerce promotes corporate innovation by improving the regional informatization level and the local commercial circulation system. The evidence from Chinese firms implies that it is necessary to strengthen the construction of information infrastructure, encourage the transformation and upgrading of traditional commercial circulation, and promote innovation of traditional business in combination with e-commerce.

The paper aims to investigate social commerce systems from a systems thinking perspective. It proposes to model the social commerce process and outlines how Following, Communicating, Purchasing, and Sharing are systematically connected with each other in the social commerce process. The paper describes an exploratory review study using the systematic literature review method, including 384 social commerce research papers, which were published from 2011 to 2021. The data are refined by documentary analysis, including Study Selection Criteria and Quality Assessment processes. The paper systematically develops a conceptual framework for understanding social commerce. Previous research on social commerce mainly focuses on one or more particular key success factors (such as trust) in social commerce, and a few of them investigate social commerce as an integral business system. This review provides a more comprehensive basis for future social commerce research.

Compared with traditional offline recycling channel, recycling through the “Internet+ recycling” platform has increasingly attracted the academic and practical intention in the past decade because of its accessibility and convenience. To promote the recycling initiatives and construct sustainable operations, how to stimulate supply chain stakeholders participating in the online recycling becomes a challenge issue. This paper considers one supplier, one manufacturer, and one third-party recycler (3PR) in a two-echelon remanufacturing closed-loop supply chain with an “Internet+ recycling” platform, in which consumers can access the online recycling platform and make an appointment for recycling without a physical visit. The manufacturer has three choices: either do not participate or participate with one of two strategies: cost-sharing (CS) or active promotion (AP) strategy. We develop a Stackelberg game model to study the motivation of the manufacturer to participate in the “Internet+ recycling” platform and the influence mechanism of key factors. The key findings include the following: (1) compared with the case without the “Internet+ recycling” platform, when the proportion of cost sharing for the 3PR is low, strategy CS contributes to the improvement of the 3PR’s performance; (2) in the presence of two participation strategies, when the disassembly rate is low enough, the manufacturer prefers strategy AP; otherwise, he selects strategy CS; and (3) a high proportion of cost sharing for the manufacturer or low promotion effort cost can increase the whole profit of the closed-loop supply chain.
