상생협력·동반성장 참여 협력사의 성과와 과신 - 행동경제학적 해석: 정성적 및 정량적 성과 갭-

As a result of the empirical analysis, the consistency of the determinants of quantitative performance according to the technical capacity of SMEs’ partners is high, but the consistency of the qualitative and quantitative empirical analysis results is low. SMEs’ suppliers value qualitative performance highly in order to continuously enjoy the free support provided by large corporations, but fail to create quantitative performance suitable for such qualitative evaluation. The difference between the qualitative performance and quantitative performance of partners can be said to indicate the existence of overconfidence from mutual growth which ignores the difference in technical skills. Llarge corporations unilaterally support their partners, but the evaluation of them on the win-win cooperation and mutual growth only reflects the survey data of SMEs' partners. Therefore, the current asymmetric evaluation, which does not consider a capability evaluation of partner companies by large corporations, must be improved to alleviate overconfidence in mutual growth. To achieve this paradigm shift, there is a need for a policy to reshuffle a win-win growth evaluation system, manpower capacity, and criteria for selecting external experts.
