This study empirically analyzed the labor income share of primary and subcontractors. The results are as follows. First, panel regression analysis showed that the variables of transaction concentration, outsourcing cost, capital intensity, and market share had a significant negative effect, while union organization rate and R & D investment had positive effects. In particular, the R & D variable had a negative effect on the share of labor income in the year of investment (t), but had a positive impact on the long-term (t-1, t-2). Second, the share of labor income during the last 11 years (2006~2016) was higher in subcontractors with lower wage levels. This analysis implies that the wage inequality between the primary and subcontracting enterprises can not be eliminated without improving the solvency of subcontractors.

The banking system provides a number of important functions for the economy and is also the lifeblood and financier of the economy in each country. Large amounts of idle money have not been exploited by banks; however, banks still depend on loans, including loans from foreign banks, to meet the growing demand, as such, for banks, the cost of capital is high, the stability and business efficiency are low and banks have not promoted their internal resources to grow steadily. To achieve the goal, this research analyzes the factors affecting the choice of bank for the deposit decisions of customers in Vietnam. The study used a sample data of 250 individuals and SPSS software was used to analyze the data. The results showed that customer policy has a positive effect on customers' deposit decisions in a bank, and this is new evidence regarding behavioral theory in the case of Vietnam. Results further demonstrated that other factors such as employee image, brand, interest rate, relative influencing, and transaction time positively impact the choice of bank for the deposit decisions of customers. However, the bank's promotion strategies had no impact on the choice of bank for the deposit decisions of customers. Besides, employee image is the most influential factor in the deposit decisions, followed by the bank's brand and interest rate.

In the current fast-growing market economy, the accounting-outsourcing trend of small and medium-sized enterprises is on the increase. Studies from both foreign and domestic sources have shown that many factors influence this decision. However, each country has different economic and political characteristics, so these factors and their degree of impact on accounting outsourcing also vary. This study aimed to determine the factors affecting the decision to outsource accounting activities of small and medium transport enterprises in Vietnam. A survey of 384 transport SMEs was conducted using the convenience sampling method. A personal interview with owners/managers/CFOs in 3 major cities of Vietnam based on a research review was conducted. The model examines the influence of many independent variables on accounting outsourcing. The multilinear regression analysis shows that the higher the Assets Specificity, the lower the degree of accounting outsourcing. In addition, the degree of outsourcing is positively and significantly related to frequency and trust in accountants. Besides, when we include control variables such as gender, administrative level, firm size, company age, education, and experience into the model. The results show that small and medium enterprises with limited resources should switch from the traditional internal accounting method to a professional accountant with external knowledge. Based on this study, the author proposes several implications for the accounting outsourcing of small and medium-sized transport enterprises in Vietnam to be more effective. Finally, this study also contributes to the basic knowledge of accounting outsourcing.

This paper presents a performance analysis model based on an M/M/1 queue and Poisson distribution of input data traffic. The simulation on a pipelined AES system with processing rate of 10 rounds per clock shows $4.0\%$ higher performance than a non-pipelined version consuming 10 clocks per transaction. Physical implementation of pipelined AES with FPGA takes 3.5 times bigger gate counts than the non-pipelined version whereas the pipelined version yields only $3.5\%$ performance enhancement. The proposed analysis model can be used to optimize cost-performance of AES hardware designs.

Governance can be defined as a concept that encompasses a series of processes including partner selection as well as control and coordination of collaboration to achieve common goals. The study examined efforts to mitigate the risks of opportunistic behaviors into partner selection, partner relationship, control mechanism, and conflict management. For cases that have achieved commercialization outputs with the participation of SMEs, data was collected and analyzed such as interviews with project managers and case records for seven months from October 2016. According to the analysis result, as the complexity increases, such as multilateral cooperation for the development of finished products, cooperation with a trusted partner rather than a partner who can perform a task well was preferred, and the process control was put ahead of the output control. Regarding the partner relationship, the relationship between the owner and the agent differed according to the point of view, and there was a lack of clear allocation of authority and responsibility as well as a reward for the result. In terms of the conflict management, most emphasis was on resolving conflicts or difficulties, and no attempt was made to utilize the positive aspects of the conflict. The structure of most industry-university-institute cooperation organizations is simply composed of the host and participating organizations, and the management regulations should be amended for companies, that put actual funds and use the outputs, to have the authority and responsibility as the owners, and be allowed to use the governance elements appropriately to take the lead as consumers.

As transaction and investment using technology are vitalized, the need for objective standards for the technology is increasing. Current technology value evaluation system is limited lacking reliability and objectivity. Besides the traditional evaluation methodology which are market approach, income approach and cost approach other diverse evaluation methodology such as real option method and royalty calculation method are being studied; however currently there are no dominant evaluation methodology in the market. Same value evaluation system cannot be applied between similar technologies because value of technology is relatively decided based on the target. Approaching through collective intelligence and crowd sourcing, in meaning of majority participant's decision can make objective and better result than handful of experts, suggest alternative to problems of such matter above. By grafting the four types of crowd sourcing model which are Wisdom, Voting, Funding and Creation, this paper will discuss the ways to enhance the objectivity of technology evaluation through direct evaluation utilizing expert group and the public's indirect evaluation.

Logistic costs refer to trade costs, but it could influence FDI as well as global trade. Multinational corporations choose the geographic organization to produce their products. Therefore, it involves many countries to produce one product. International trade between countries more frequently involves the trade of raw materials, components, and unfinished goods. This implies that countries with better logistic performance are attractive for investment because of low transaction costs. Using the logistic performance index provided from the World Bank, this paper investigates the impacts of logistic performance on FDI inflow to developing countries. Results show that infrastructure and timeliness have a positive effects on FDI inflow to low income countries. In the case of middle income countries, timeliness has a negative effect on FDI inflow. This discrepancy between the low- and middle- income countries comes from the different motivation. FDI for low income countries primarily attempts to minimize labor costs. However, FDI for middle-income countries seems to be motivated to reduce labor costs and expand sales markets. FDI inflow in low-income countries serves as part of the offshoring or global outsourcing of multinational corporation.

The fourth industrial revolution is affecting the industry as a whole, and the current logistics industry is coexisting with crises and opportunities. As part of overcoming this situation, the online platformization of the logistics market has recently been rapidly taking place, and the growth of e-commerce around developed countries has emerged as a demand for flexible freight services that can send and receive cargo anywhere and anytime at appropriate cost. However, the logistics industry has not been able to change rapidly in line with the demands of the market as it is immersed in traditional transportation transactions. Thus, the digital transformation of the freight market has become urgent to address problems such as uncertainty over traditionally closed and conservative freight market transaction processes and the lack of reliability caused by information asymmetry. Therefore, innovative domestic and foreign companies are attempting to establish a new way of transporting cargo, especially a marketplace way of connecting suppliers and consumers. Current status analysis and case studies were conducted through existing literature surveys, and prior research on freight market place selection factors was previewed, and the selection factors were stratified into five upper and 19 lower factors. Through this study, it is expected that improvements for sustainable growth of freight marketplace companies will be derived and that it will be a basic study of establishing management strategies through marketplace operation and quality control. In addition, it is deemed that the priority of customer requirements can be actively accepted, providing an opportunity to actively respond and strengthen corporate competitiveness.

This study is to analyse how trust and asset specificity among partner firms affect on performance of international joint venture(IJV). Especially, the analysis was mainly based on a quadratic model. While it assumes that the previous studies was based on linear model in the relationship between trust, asset specificity and the performance, this study proceeds a empirical analysis by setting up a hypothesis; it would be quadratic relationship between trust, asset specificity and performance which are based on social capital theory and transaction cost theory. The survey was held with 74 manufactures who were established as an IJV by Korean and foreign firms together. In the result of the empirical analysis, trust shows an inverted U-shaped relationship with IJV performance. Also, asset specificity shows the U-shaped relationship with IJV performance. The results suggest that it needs to control and maintain the trust level among the partners in order not to lose an appropriate control caused by too much trust. In order to minimize the cost generated by asset specificity and to transform it into positive impact, it needs a control and the operation of monitoring system on the opportunistic action of the partners. Furthermore, it needs to keep organizational flexibility and innovativeness to continuously develop new capabilities.
