In the complex environment of the IoT (Internet of Things), the amount of information available is enormous and the number of users also increases at a blistering pace. With a huge number of users, e-commerce marketing strategies in the IoT become extremely important and must be altered accordingly in response to changes in the environment and industry. Hence, the application of IoT technology to mobile commerce allows users to receive integrated information according to time, location, and context using location-based service, and provides them with a more effective shopping experience. The validation results show that external variables indirectly influence behavioral intention through perceived usefulness. The investigation of behavioral intention is used to understand users’ acceptance and using willingness of the store app, which can help narrow the gap between stores and consumers, and help improve operations.

To maintain competitiveness, businesses need to upgrade their operational performance and financial performance more efficiently and effectively in order to control uncertainty and costs. The purposes of the study are to (1) investigate the relationship between three dimensions, namely integration, flexibility, and performance; and (2) examine the mediating effects of supply chain flexibility. This research collected annual reports from the Indonesian basic and chemical industry from 2014 to 2017. Content analysis was used to extract information from companies’ annual reports, and hierarchical analysis examined the hypotheses. The results show that external information integration positively influences both reactive and proactive flexibility. Furthermore, proactive flexibility significantly affects financial performance and operational performance. Moreover, both reactive and proactive flexibility have positive mediating effects on the connection between external information integration and operational performance. Lastly, reactive flexibility positively mediates external information integration’s effect on financial performance. As the market has been becoming more competitive, this study provides important insights for decision-makers. This study contributes to the knowledge of the Indonesian basic and chemical supply chain by considering both financial and operational performance, especially as these performance indexes measure different dimensions.
