报告简介：

We explore how value chain participants can leverage the potentialbusiness value brought by the network effects of connectedproducts with marginal production costs. We examine a classic two-tier valuechain of a connected product that exhibits network effects. First, wepresent a benchmark model of a decentralized value chain operated through thewholesale price contract and demonstrate how the presence of network effects improvesprofitability and efficiency. Next, weexplore two representative strategies value chain participants can employ tofurther exploit network effects: networkexpansion and engineering network strength. We find that these two strategieshave a complementary relationship as the marginal production cost of the productdeclines. Finally, we investigate the impact of adopting these strategies on theefficiency loss of thedecentralized value chain compared to the centralized one. The results suggestthat both strategies could either increase or decrease such efficiency loss, anda decentralized value chain might bring about larger social welfare undernetwork effects.
