Purpose: Support policies for small and medium-sized retailers (SMSRs) have been promoted in various ways over the past 20 years, but they are generally regarded as unsuccessful. The purpose of this study is to analyze the process and impact of policy changes, identify the reasons for the lack of success, and explore policy alternatives. Research design, data and methodology: This study explored major policies in various categories such as the retail industry, traditional markets, and Micro-Enterprises from the mid-1990s to the present. It also analyzed the short- and long-term impacts of major policies at the retail format level like SMSRs, using data from Statistics Korea's service industry survey. Results: This research found that sudden shifts in policy philosophy conflicted with the existing market structure and reduced the effectiveness of policies. It also found that policies aimed at improving competitiveness at the SMSRs-level had some effect, while polices aimed at supporting expenses at the individual store-level were difficult to achieve their intended purpose. Conclusions: The failure of the policy to support SMSRs is fundamentally due to the late response and conflicts between policies. It was also not successful due to the policy's focus on individual store-level expenses and maintaining employment rather than structural improvements of SMSRs format.

Preventive maintenance(PM) is an action taken on a repairable system while it is still operating, which needs to be carried out in order to keep the system at the desired level of successful operation. In this paper, we consider a Bayesian approach to determine an optimal periodic preventive maintenance policy. When the failure time is Weibull distribution with uncertain parameters, a Bayesian approach is established. Some numerical examples are presented for illustrative purpose.

It is important to obtain the information of population center for establishing the balanced development policy of a nation. In this note, the population center of Korea is obtained using 2010 Census data and compared with the past population centers. The weighted average method is used for calculating the population center. The results of this note will be able to contribute in the regional population distribution policies.

This paper considers a Bayesian approach to determine an optimal PM policy with random maintenance quality. Thus, we assume that the quality of a PM action is a random variable following a probability distribution. When the failure time is Weibull distribution with uncertain parameters, a Bayesian approach is established to formally express and update the uncertain parameters for determining an optimal PM policy. Finally, the numerical examples are presented for illustrative purpose.

This paper presents a model for determining the optimal number of minimal repairs before replacement. The basic concept parallels the periodic replacement model with minimal repair at failure introduced by Barlow and Hunter, only difference being the replacement signalled by the number of previous minimal repairs performed on the unit. In the case of Weibull distribution, which is widely used as a general failure distribution, the optimal solution could be obtained numerically and seems more cost effective compared to the Barlow and Hunter's Policy II.

By the research seen by examining plan which can improve at least systematization of a distribution sector, reform opening got into stride to Chinese distribution channel structure by improvement of a premodern Chinese circulation system and non-efficiency-structure. The competition means of the China distribution industry, the development direction, and the Chinese distribution channel strategy are received focusing on the 1990s, and it is going to show a way proposal.

In this paper, we find optimal policy for the (Q, r) inventory model under the lead time uncertainty. The (Q, r) inventory model is such that the fixed order quantity Q is placed whenever the level of on hand stock reaches the reorder point r. We first develop the single level inventory model as the basis for the analysis multi-level distribution systems. The functional problem is to determine when and how much to order in order to minimize the expected total cost per unit time, which includes the set up, inventory holding and inventory shortage cost. The model, then, is extended to the multi-level distribution system consisting of the factory, warehouses and retailers. In this case, we also find an optimal policy which minimizes the total cost of the contralized multi-level distribution system.

Purpose - We investigate the relationship between economic policy uncertainty (EPU) of the US and China and housing distribution economy in Korea using EPU indexes of two countries and the economic indicators in Korea. Research design, data, and methodology - We use the data such as the Korean housing price stability index (HPSI), housing purchase price index (HPPI), housing lease price index (HLPI), banking stock index (BSI), and consumer price index (CPI) with EPU indexes from January 1999 to December 2017. As an empirical methodology, we select the vector error correction model (VECM) due to the existence of cointegration. Result - As results of the impulse response function, the impact of the US EPU index has initially a negative response on the Korean HPSI, HPPI, and HLPI referring the housing distribution market including the economic variables, BSI, and CPI. Likewise, the impact of index in China has initially a negative response on economic indicators except the BSI in Korea. Conclusions - This study shows that the EPU index of the US has significantly negative relationships on all economic indicators in Korea. In this study, we reveal EPU of the US and China has dynamic impact on housing distribution economy returns in Korea.

Purpose: This study analyzed the policies on and changes of elite training through overseas study and their impact on China's national development when entrepreneurs return home. In particular, it analyzed returnee entrepreneurs in the distribution industry. Research design, data and methodology: This study largely analyzed the Chinese government's policy of attracting foreign talent and the results of the policy. The research method utilized the Chinese Statistical Yearbook and various literature. This study also used case analysis methods for start-ups by haigui in the distribution industry. Results: According to the analysis, the Chinese government is implementing various policies to attract talent. Representatively, the government actively attracts talent through the Hundred Talents Plan, Thousand Talents Plan, Chunhui Program and Chizi Program. In addition, the Changjiang Scholars Program is attracting foreign talent. As a result, many talented people are leading development of the Chinese economy. Conclusions: The Chinese government is actively pursuing policies to attract talents from overseas. In addition, it has established a system in which government ministries and research institutes can work closely together to secure effectiveness in attracting overseas talents. Through this, overseas talents are playing an important role in China's economic development through new start-up activities including the distribution industry.

Purpose - The purpose of this research paper is twofold. First, this paper attempts to grasp the damage caused to small and medium-size retail traders from online wholesalers in the field. Second, this paper engages in a psychological characterization of the enterprise spirit and the management of small and medium-size entrepreneurs in the retail trade business that are harmed by online wholesalers. Research design, data, and methodology - Data on three large Korean wholesalers engaged in ongoing litigation during the first half of 2014, including E-Mart Traders E-Club, and regarding applications for business adjustments from three large wholesalers were used. Results - The results show that small and medium-size distribution merchants seek political support for facility modernization, policy-specific funds, development of the distribution of PB products, advanced distribution techniques, joint logistics systems, establishment of distribution and logistics centers, sharing of parking facilities, and joint ordering systems. Conclusions - This study examined the damage to, and the government's support of policy demands from, small retail traders.
