  • Many researchers have discussed on a policy establishment to revitalize a regional industry of a domestic ecosystem. However, it is rare to consider activation measures and priorities that are appropriate for local characteristics. Therefore, this study conducted a qualitative study to gather and analyze the views of expert groups in order to derive measures to revitalize the automobile industry in Gwangju. We examined the current status of the automobile industry in Gwangju based on a literature survey and in-depth interviews and what kind of crisis there is. We then derive strategic candidates for activation measures to address this. In addition, the relative importance and priorities of the methods derived using AHP techniques were identified. This leads to five strategies on which methods should be applied first. This will be used as the basis for future strategy development.

  • Many of logistics-related research in automobile industry has focused on inbound logistics and procurement. Research into outbound logistics is relatively few. As a starting research into outbound logistics in automobile industry, this paper examined its logistics network problems with three aspects - location strategy, inventory strategy and transportation strategy. We proposed alternatives of logistics network design resolution, and presented three practical scenarios based on those alternatives. Based on interview, on-site visit and internal data collection processes, we identified major domestic outbound logistics problems such as redundant logistics bases, inefficient delivery policy, insufficient inventory capacity, inventory stock quality deterioration, inefficient transportation system, and etc. In order to cope with those problems, we proposed such strategic alternatives as introduction of hub-and-spoke system, integration of logistics bases, introduction of (automatic) parking building, diversification of transportation mode, and etc. At the same time, we constructed three practically executable scenarios based on those ideas. The first is "Center Hub" scenario, the second is "Metropolitan Hub" scenario. The third and last scenario is "Regional Consolidation of Warehouses (distribution centers)".

  • After the establishment of WTO for strengthening of GATT in 1995, the world economy has gradually been integrating toward economic globalisation. Even though this multilateral agreement may be beneficial to many countries but it also interferes domestic policies of member countries and threatens the role of local government and policy independence. For these reasons, FTA between countries or regions has been increasing. According to this trend, Korea and China has reached a substantial agreement of Korea-China FTA for mutual benefits. In general, the Korean automobile industry will benefit from Korea-China FTA due to its competitiveness in the global market and improvement of market access. However in the provisional schedule of concessions and commitment reported by press, the automobile seems to be excluded in this schedule of concessions. Hence, Korean automobile industry can not use the price competitiveness from tariff elimination. Therefore, Korean automobile industry needs aggressive marketing strategies for enhancement of brand equity as well as development of environment-friendly cars for following environment policies of Chinese government. Furthermore, they should make efforts to create the efficient investment environment by the removal of non-tariff barriers.

  • The world's electric automobile sector has shifted beyond technological environmental changes to a stage that has an impact on the market environment. And automakers are shifting from the existing strategy of "technological advantage → brand enhancement → sales expansion of existing internal combustion engine vehicles" to the expansion of the electric automobile market itself, which is to enhance market competitiveness. In addition, competition in the electric automotive parts market is expected to intensify due to the expansion of the business areas of existing parts makers and the entry of new companies, and development cooperation is expected to actively proceed to improve the efficiency of major eco-friendly parts. Along with this prospect, electric vehicles are expected to change the overall structure of the automobile industry, the overall growth of the electric vehicle value chain such as batteries, power trains (motors, power management and control systems), electric vehicle production, and charging infrastructure Is expected. Therefore, in this thesis, in order to cultivate a variety of high-quality human resources that companies want to keep pace with the changing automobile industry, we study a professional manpower training program that leads the growth engine of the electric automobile industry.

  • Iran has been focused on FDI by global automobile companies after the economic sanction on Iran was removed except primary sanction. In this paper, some strategies for Korean Automobile Industry to branch out into Iran are suggested. For the purpose, Iran's automobile industry and characteristics are examined. The market situation is analyzed qualitatively and quantitatively. In passenger cars sector, Korean automobile companies would be better to wait and see the development of US-Iran relationships while exporting CKD sets of cars to Iran. It can be a good strategy, however, to put parts companies into Iran first because of Iran Government could be displeasing with exporting CKD only. FDI, licensing, and joint venture are all available for the parts companies. Motor companies can clear the regulation of auto-parts localization proportion by the method. The parts companies will be able to do key roles as supply chains after OEM branch out into Iran. It is also advisable to upgrade outpost in Iran into frontline for exporting cars to MENA area. In such a case it will be a prerequisite to develop a role-division model with facilities in East Europe. It could be called Parts first-then cars strategy. In commercial cars sector, it can be suggested to leverage natural gas as a link to branch out into Iran. Iran government wishes to develop natural gas resources. The strategy can be summarized that automobile companies carry out producing CNG buses in Iran while energy companies are drilling and producing natural gas.
