摘要 Abstract of the paper	This paper focuses on how the final goods are produced by two complementary inputs influence s the incentives of a vertically integrated firm that licenses the production technology of its core input to an external firm, transforming the licensee into an input supplier. We find that the licensor strategically faces a higher wholesale price through vertical licensing than with in house production so as to lower the price of complementary input when the products are differentiated. We also show that the vertical licensing always occurs even when the licensor offers the agreement for free. Moreover, when the final goods are transformed by multiple complementary inputs the wholesale price is set above the upstream marginal cost is more likely occurs. From the view of welfare, this causes double marginalization and welfare reduction even industry profit in the downstream market increased, which is a conflict of the interest between the licensor and the society’s desire.
