In this paper,an incomplete information static game theoretical model is set up to do the research of a monopolizer s R&D optimal deterrence strategy when the monopolizer can use pre-emption deterrence strategyand nonce deterrence strategy,and their products have strong network effect on consumer s choice behavior.

研究结论表明:在面临潜在进入威胁的情况下,如果R&D行为是一种开创性发现或发明时,垄断企业采用不阻挠战略;如果R&D行为是一种渐进式创新行为时,垄断企业采用提前阻挠战略是最优的;而不同程度的潜在进入威胁引致的阻挠策略是存在区别的,当垄断企业认为进入者进入概率很大时,其最优阻挠行为是快速阻挠;当垄断企业认为进入者进入概率很小时,其最优阻挠行为是慢速阻挠。
