Cost-reducing innovation uses two types of technologies; the firm specific technology and the complementary technology. We examine the efficiency of firms\u0027choices of technology types when firms cooperate with respect to the complementary technology. The main findings are as follows. In the industry with the higher (lower) technological complementarity, firms overinvestment (underinvest) in the firm specific technology and underinvestment (overrinvest) in the complementary technology. In the industry with the higher technological complementarity, firms tend to gain more profits when the degree of product differentiation is high. The opposite may occur when the degree of product differentiation is low.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d",
