PURPOSES : The purpose of this study is to identify the beneficiaries of car-sharing that can utilize autonomous car-sharing services when they are introduced. METHODS : This study was conducted in two stages. The first step was to analyze the characteristics of shared car usage by region and rental time using t-Ttest. The second step was to analyze the beneficiaries of autonomous car-sharing services if they are introduced. The beneficiaries were derived using parking time and survey data. RESULTS : Car-sharing behavior showed statistically different usage characteristics by region and rental period. However, the distance traveled per trip for short trips was similar. When the autonomous car sharing service with free return and rental is introduced, 31% (Jeju) to 38% (Daejeon) of short-term renters and 50 to 52% of long-term renters are expected to benefit. CONCLUSIONS : When introducing autonomous car-sharing services, it is necessary to establish a shared car strategy that reflects the characteristics of car-sharing use by region and rental period. In particular, in Jeju Island, where the rental time is relatively longer than Daejeon, the introduction of autonomous car-sharing services will contribute to reducing the cost of shared vehicles in terms of cost.

This study explains an agricultural mobile commerce case using Oauth Based Real-Time Information Sharing Technique according to the growth of the agricultural e-commerce market. Considering the characteristics of the agricultural market, it can confirm differential values with the existing agricultural mobile commerce market according to the functions and characteristics of its technique. We compare variables for introducing agricultural mobile commerce with the existing mobile commerce. Trust through information sharing with real-timefarming diaries, suitability and perceived ease of use variables are positively influenced, but influence on completeness and authority of information variables are relatively insufficient. Through this, we explained differential values of agricultural mobile commerce and suggested an applicable business model.
