This study is an empirical analysis of export performance according to the type of GVC participation and governance of Korean manufacturing companies. Based on panel data from KOSPI listed firms, it was analyzed that relational investment, information exchange, and innovation affect the level of supply chain integration and corporate performance with the moderating role of trust. In addition, it was found that the degree of integration of the supply chain affects GSCM's performance and export performance. In case of the type of GVC governance, it was analyzed that the higher the integration strength, the higher the performance compared to other types. This result shows that trust-based supply chain integration and continuous GVC investment are very important. This explains that high levels of GVC governance, along with high integration strength, can lead to successful GSCM performance. Innovative investment strategies based on the relationship capabilities and trust levels of GVC participating companies can have a positive effect on the degree of global partnership formation and integration.

Supply chain management (SCM) has been regarded as one of the most critical issues in the current business environment. Moreover, supply chain partnerships between suppliers and buyers in SCM have had a significant impact on supply chain performance. In this paper, we conduct a quantitative analysis for supplier-buyer's profit sharing and pricing policies based on supply chain partnerships. For this purpose, we assume that a two echelon supply chain with a single supplier and a single buyer is given and the buyer faces deterministic demand which is not only a function of buyer's selling price, but also strictly decreasing, concave, and twice differentiable function. Then we will prove the following. Firstly, without supply chain partnerships, there exist supplier and buyer's selling prices per unit such that their total profits are maximized, under the assumption that buyer's order quantity is exactly equal to the demand buyer faced. Secondly, buyer's selling price per unit which maximizes supply chain's total profit with supply chain partnerships is lower than buyer's selling price per unit which maximizes buyer's total profit without supply chain partnerships. Thirdly, given supplier's selling price per unit. buyer's total profit without supply chain part nerships is greater than that with supply chain partnerships, whereas the opposite case happens for supplier's total profit. Finally, there exists supplier's selling price per unit which makes the maximum total profits for both supplier and buyer with supply chain partnerships greater than those obtained for any given supplier's selling price per unit without supply chain partnerships.
