This study investigates a co-opetition-type dual-channel supply chain that consists of a competitive supplier (CS) and a capital-constrained manufacturer (CCM). The CCM procures key components from and simultaneously competes with the CS in the consumer market. To address the CCM's capital constraint, we consider three financing strategies, namely, trade credit, bank loan, and hybrid financing (i.e., combined use of bank loan and equity financing). Game models are established to characterize the interactions between the CS and CCM. The corresponding equilibria are derived under each strategy. Then, comparative analyses are conducted, and the CS's and CCM's preference structures regarding the three strategies are revealed. On this basis, the equilibrium strategy can be concluded as either trade credit or hybrid financing, but never bank loan. Specifically, when the equity financing ratio is small or large, trade credit is an equilibrium strategy. When the equity financing ratio is medium, the equilibrium strategy between trade credit and hybrid financing is determined by consumers' product preference and loan interest rate.accounted for a combined shipping volume of over 533 million units in 2017. This value is equivalent to 36.3% of the global smartphone market. 2 Although the two companies are in fierce competition in their industry, they cooperate with each other in many areas. 3 Notably, Samsung has provided Apple with processors and OLED screens for many years. 4 Such "co-opetition" is prevalent in many high-technology industries. Other typical examples are IBM and Cisco. The former purchases network equipment from the latter, while simultaneously competing in the overall server market. 5 The dual-channel supply chain, in which a supplier provides a manufacturer with key components while the two companies compete with each other in the final market, is common in real businesses. However, in practice, certain manufacturers in such dual-channel supply chains may lack capital to support production. For example, the smartphone screens used by Gionee, a well-known smartphone manufacturer in China, have always been provided by Foxconn. However, in recent years, Gionee has encountered capital-shortage problems and sought financing instruments to support its production. Consequently, one of the critical challenges for Gionee is selecting a suitable financing strategy.Accordingly, we extend the current literature by examining a co-opetition-type dual-channel supply chain, which consists of a competitive supplier (CS) and a capital-constrained manufacturer (CCM). The two firms are cooperative in component supply but competitive in the consumer market. Specifically, the CCM procures components from the CS. Meanwhile, the two companies compete by selling substitutable products in the same consumer market. For the capital constraint of the CCM, we consider three financing strategies. In Strategy 1 (trade credit), the CS offers trade credit to the CCM. In Strategy 2 (bank loan), the CCM seeks a bank loan to support its ...
