In the platform-based sharing economy service, the consumer using the service and the service provider providing the service form a two-sided market around the platform. In the two-sided market, service users and service providers interact across the platform, and the value of the platform increases with the size of the network. This study aims to study the virtuous circulation of consumption and production for sustainability of sharing economy. For this purpose, several hypotheses were established based on the literature and are tested with survey data of both consumer and service provider of Airbnb. Structural equation modeling is used to analyze whether the consumer acceptance intention model and the supplier acceptance intention model can be linked through the concept of network effect, which is a major characteristic of the sharing economy service platform. The research results are expected to contribute to development of a sustainable sharing economy model.

Hermetic sealing is an important technology for isolating and protecting air-sensitive materials and is key in the development of foldable and stretchable electronic devices. Here we report an ultra gas-proof polymer hybrid thin layer prepared by filling the free volume of the polymer with AlO using gas-phase atomic layer infiltration. The high-density polymer-inorganic hybrid shows extremely low gas transmission rate, below the detection limit of the Ca corrosion test (water vapor transmission rate <10 g m day). Furthermore, because of the remarkable nanometer-scale thinness of the complete polymer-inorganic hybrid, it is highly flexible, which makes it useful for hermetic sealing of stretchable and foldable devices.
