The current article examined the factors and effects of trust in the online social platform using consumer-generated media (CGM) through a literature review. Since trust is a critical factor in developing and maintaining all forms of relationships, understanding the factors and impacts of trust-building with autonomous CGM is important for the formation of sustainable online services. Literature was selected and examined according to the criteria and analyzed using the ADO framework. From the examined results of the literature review, it was depicted in prior research that, perceived trust mediates between antecedents and the subsequent purchase intention. Because participants voluntarily provide information, this result supports the implication that “Trust promotes mutual assistance, which is the intrinsic form of online social platform, by mediating between factors in CGM services and contributing to the service building with the participation of all actors. This will promote the eco-system of services and contribute to the business.”

The concept of smart sharing cities, which was recently introduced within the field of urban planning, has evolved in line with the continuous advancement of Information and Communication Technology (ICT), the expansion of the sharing economy, and the urgent need to pursue sustainable development. However, a new indicator framework is required to help cities to monitor their performance and formulate plans to guide the process of transforming into smart sharing cities. Accordingly, we aimed to develop an indicator framework for a smart sharing city by clarifying and refining the characteristics of existing indicator frameworks for sustainable cities. We reviewed policies for promoting ongoing sharing activities in two cities, Seoul and Kitakyushu, focusing specifically on the shared mobility and shared built environment sectors.
