摘要 Abstract of the paper	We examine the influences of introducing an online firm into a market with two physical firms on equilibrium levels of quality R&D, optimal regulated prices, physical firms’ location choices, and welfare under regulated prices. By introducing an online firm such that competition in the market becomes more severe, we derive the following interesting results. First, we show that intensifying competition will lower the equilibrium level of quality R&D comparing with the case under the absence of online firm. This result is in support of Schumpeter (1943) argument. Second, the optimal regulated price for the physical firm in the former will become lower, and meanwhile it equals the optimal regulated price for the online firm plus the marginal cost of the physical firm. Third, physical firms’ optimal locations will change from agglomeration at the center of the line segment to separation. Lastly, the welfare in a market becomes higher.
