This study purports to analyze the structural relationships through post acceptance model among eight exogenous factors influencing continuance intention to use of mobile game and expectation confirmation, perceived usefulness, user satisfaction and continuance intention to use. For this study, a survey is carried out the Chinese university students who are playing mobile game, and total 275 data were collected and analyze the data through AMOS 23.0. Several results were derived through empirical analysis. The results of this study are expected to provide a few implications to Korean game companies that want to enter the Chinese mobile game market in the future on how to secure and maintain local customers in China.

The aim of this study is to analyzed the comparative assessment on the fast payment system of USA. The paper is organized as fellows. In Section Ⅰ, I outline the purpose of this paper. In Section Ⅱ, I explain previous research in domestic and foreign literature and conduct the construction process and development. In Section Ⅲ, I did comparative analysis the operational policies between RTP network and FedNow of America. In Section Ⅳ, I assessed the usefulness both fast payment system. In Section Ⅴ, I summarizes and suggested that the payment system have to assume, with good reason, more efficiently accurately and securely operation together with conclusion. The results of analysis is to fellow. FedNow is operated by federal reserve bank, while RTP network is owned-operated by The clearing house.

On account of COVID-19 which broke out in December 2019, normal economic activity has been considerably impeded. Namely, consumer sentiment has been shrunken by social distancing and movement across national border has been blocked. The empirical analysis shows that small/medium exporters & importers in Busan have also suffered damage in trade and employment. The smaller companies suffer larger damage due to the own characteristics of Busan - many small & medium manufacturers. However, companies which use non-contact online export channel have suffered less damage. It was found that the COVID-19 damage of small/medium companies in Busan was not caused by problem in trade procedure like delayed custom clearance, but by difficulty in trade process like reduced consumption or procurement of raw materials. It is time for government to support digital conversion of small/medium companies in order to prepare for long term COVID-19. The government should support manpower & equipment so that they may build online platform or should improve the effectivity of public platform so that they may use it more.

The study investigates the question of how firms’ external factors affect their selection of export market using survey-based data for 252 renewable energy technology firms in Korea. Considering the situation and reality where each country, including Korea, employs policy mix to promote renewable energy technology industry, firms are actual beneficiaries and core economic entities of export, and renewable energy technology market is growing, we established a binary logistic regression model to test the effects of public policies(renewable energy industrial policy, environmental policy, and export promotion policy), social acceptance, trade association support, market attractiveness, and inter-firm competition on firm-level export. After confirming the reliability and validity of the items to measure each construct, we test the relationships between the variables to be examined. This study shows the Korean renewable energy technology firms’ export is affected mainly by two public policies and industry factor, environmental policy, export promotion policy, and supports of trade association. However, renewable energy industrial policy, social and market factors(social acceptance, market attractiveness, inter-firm competition) do not significantly affect firm-level export. We propose policy implications based on the results of the study, and list the limitations that should be addressed in future research.
