This paper investigates the effects of corruption and long-term investment of businesses in Vietnam using the General Least Square (GLS) estimation method for businesses in 63 provinces in Vietnam from 2016-2018. The results show that corruption was an important factor affecting the long-term investment decisions of Vietnamese enterprises. The ability to predict corruption of businesses can explain the phenomenon of part of the cash flow of businesses flowing out of production and business. Informal costs related to low-level administrative procedures act as “grease” to help businesses reduce time costs, but when the total amount of unofficial expenses exceeds 10% of revenue of businesses, they become a burden for businesses and restrain them from making long-term investments. Corrupted public officials' behavior has led businesses to misallocate resources and prevent them from making long-term investments. The result shows that the East Asia paradox holds only for the case of informal costs related to administrative procedures in Vietnam.

This study analyzes the factors affecting the intention of using mobile applications (apps) for room-sharing in Vietnam. The research model is inherited and developed based on the unified theoretical model of technology acceptance and use (UTAUT2) by the specific conditions of Vietnam. The analysis results from 346 users show that the intention to use mobile apps for room-sharing services in Vietnam is influenced by expected benefits (i); expected effort (ii); social influence (iii), hedonic motivation (iv), trust (v), and perceived security (vi). Expected benefits, hedonic dynamics, and expected security have an important influence on the using intention among these factors; thus, application providers need a valuable solution to enhance the functionality of their applications on these aspects to meet the customers' increasing requirements.
