本研究从理论上考察了垄断性最终产品企业与其他最终产品企业之间的免费技术共享效应。我考虑两种情况：第一，在最终产品市场上存在一个最终产品公司;第二，在最终产品市场上存在两个最终产品公司。在企业自由进入差异化中间产品市场的情况下，当另一家企业进入最终产品市场并将其转变为两家企业的寡头垄断时，由于中间产品企业数量的增加，成本效率提高。此外，不仅在两个企业的寡头垄断中，而且在三个或三个以上企业的寡头垄断中，在位企业的利润都有可能增加。因此，本研究的结论是，免费的技术共享可以提高在位企业的利润。当越来越多的公司进入中间产品部门对最终产品单位成本的影响很大时，免费技术共享有利于在位公司的利润。虽然以前的一些研究表明，企业有可能通过许可证和技术的提供来增加利润，但本研究认为，在一个经济体中，技术是免费共享的，其中差异化的中间产品企业的数量是内生决定的。
The present study theoretically examines the effects of free technology sharing by a monopolistic final-goods firm with other final-goods firms. I consider two cases: first, where there exists one final-goods firm in the final-goods market and second, where there exist two final-goods firms in the final-goods market. Given the free entry of firms into the differentiated intermediate-goods market, the results show that when another firm enters the final-goods market and transforms it into a two-firm oligopoly, cost efficiency improves because of an increase in the number of intermediate-goods firms. Furthermore, there is a possibility that the incumbent firm’s profits increase not only for a two-firm oligopoly, but also for an oligopoly with three or more firms. Thus, this study concludes that free technology sharing can improve incumbent firms’ profits. When the impact of an increased number of firms entering the intermediate-goods sector on the final good’s unit cost is high, free technology sharing benefits incumbent firms’ profits. While some prior studies show the potential for firms to increase their profits through licencing and the provision of technology, this study considers that technology is shared free of charge in an economy where the number of differentiated intermediate-goods firms is endogenously determined.
