中文摘要：
为了研究在Stackelberg寡头竞争模型下企业在产品市场是否合作对市场绩效的影响,建立了寡头市场中面向R＆D工艺的两阶段博弈模型。采用逆向归纳法求出了产品市场合作与不合作两种情况下的古诺-均衡解。研究表明,从促进技术进步的角度来看,对于R＆D效率不太高的R＆D项目,产品市场合作策略优于产品市场竞争策略。从提高企业利润的角度来看,对于R＆D效率较高的R＆D项目,当产品差异不大时,产品市场合作策略优于产品市场竞争策略;当产品差异较大时,产品市场竞争策略优于产品市场合作策略。对于R＆D效率较低的R＆D项目,产品市场竞争策略优于产品市场合作策略。从提高消费者剩余以及改善社会福利的角度来看,对于R＆D效率较低的R＆D项目,产品市场竞争策略优于产品市场合作策略。
英文摘要：
A two-stage game model is established in a stackelberg structure market directed at the R＆D （research and develop- ment） process for studying the influence on the market performance of which the enterprises set cooperation or noncooperation in the product market. Using find the cournot-equilibrium solution is found adopting in cooperation and non-cooperation this two product- market situations adopting backward induction. Study shows that product-market cooperation strategy is superior to product market competition strategy for R＆D projects with not too high R＆D efficiency from the perspective of promoting technological progress. From the perspective of improving enterprises profit, product-market cooperation strategy is superior to product market competition strategy for R＆D project with high R＆D efficiency on low differences product. For R＆D project with high R＆D efficiency on distinct diff- erences products, the resuh is reversed market competition strategyis superior to product-market cooperation strategy for R＆D project with low R＆D efficiency. Product-market competition strategy is superior to product-market cooperation strategy for R＆D projects with low R＆D efficiency, from the perspective of improving the consumer surplus and social welfare.
