It is expected that a significant change will occur in auto parts business relationship thanks to the emergence of eco-friendly cars and smart car. It means that the powertrain changes completely, leading to the replacement of the engine parts with new parts. Because of their different characteristics of various electrical components underlying the smart vehicle from the existing machines, electrics and electronics manufacturers would become major suppliers.

As a result, it seems that the emergence of next-generation vehicles such as green cars and smart car will bring about drastic change in the auto parts business relationship.

This study strive to present a desirable form of business relationship by considering the characteristics of the next generation of automotive parts, based on the type of business relationship which has been presented in the existing theory.

In the auto parts of eco-friendly vehicles, the characteristics of the product architecture and the importance of the motor make it more likely that in-house production car maker and subsidiaries would be done.

In case of secondary battery, a high level of expertise is required while related industries are already developed. In this regard, parallel trade cooperation would be desirable. For other electrical equipment such as inverters, it would also be desirable to induce cooperation agreement in horizontal in a way to secure technical capabilities by specializing in these areas of some of the existing electrical equipment manufacturers. For ECU, subsidiary deal is suitable as it is integrated product architecture that is responsible for control of the system and has a close relationship with customers.

In the case of next generation auto parts, it seems that a rise to global market leader would be determined depending on how to make an effort in the future. First, parallel trade relations in areas such as motor, secondary battery the automotive semiconductors would result in development of global a super-sized automobile parts manufacturer. Therefore, government should actively support small and medium sized enterprises to expand into new business areas or create of their business. In order to fully support the collaborative research between IT and related parts manufacturer specializing in automobile manufacturers it is necessary for government to put a priority on the consideration of such the collaboration the course of the excavation task.

In the areas of next-generation automotive, notably, a smart car, there might be the apperance of various items that small and medium enterprises require. In supporting IT integration of the automotive industry, it is necessary, not only to expand the range of their support, also strengthen cooperation with manufacturers of finished vehicles and large parts. It is also required to expand a function to exchange and provide information for auto parts manufacturers and IT companies to participate in the field of next-generation automotive parts exchange and provision of information. In addition, it is necessary for more broadened measures to discover a variety of automotive IT products, and help consumers in conjunction with product.
