【摘要】 在“一带一路”新的市场形势下,我国企业进一步走向国际市场,同时也面临着一个更加激烈的市场环境,企业间的研发合作与竞争也越发地频繁和激烈。在这一竞争洪流中,创新能力成为企业脱颖而出并保持市场份额持续增长的最重要的原动力,同时也是决定企业市场利润的核心因素。然而,相对于国外企业而言,我国企业的研发实力仍有待进一步提高。此外,由于我国对企业研发能力的研究相对起步较晚,企业研发领域的研究仍有待进一步丰富。已有的研究中,技术溢出、合作程度及合作方式等对企业效益影响缺乏深入剖析,同时,采用现行研发概率函数与现实中企业非线性研发概率的事实并不相符。因此,本文以双寡头企业研发投入策略为研究对象,加之技术溢出、非线性研发成功概率函数与成本分摊方式,构建了双寡头企合作研发与否几种具体情况下企业的研发决策模型并进行仿真对比分析,为我国企业实现研发效益最大化提供具有可行性的建议。本文以市场竞争不断加剧、对企业研发创新的需求更加迫切为研究背景,在充分梳理和总结了国内外有关文献的基础上,通过模型的构建与数值仿真分析,对垄断企业单阶段决策和两阶段决策的对、进行产量竞争的两寡头企业间考虑技术溢出情况下合作研发与单独研发、双寡头合作研发中不同成本分摊方式以及非合作与合作双寡头利润进行了系统地的对比分析,进而得到了非合作的双寡头企业在都研发但无技术溢出的决策下可获得最大利润,合作双寡头在选择基于成本下降的成本分摊方式下双方都能获得更多利润。首先,在相关理论及研究的支撑下,设计了研究整体思路及架构,建立了理论模型,分析了完全垄断条件下单阶段与两阶段决策中研发投入对企业利润的影响,构建模型并设定仿真参数,为后续建模及仿真分析奠定了基础;其次,在已有研究的基础上,加入技术溢出因素和非线性概率函数,对模型进行更加具体的划分,通过模型仿真分析可得,产量竞争市场中,非合作双寡头在同时研发但完全没有技术溢出的情况下会分别获得最大市场利润,在两企业分别投资研发存在相互技术溢出的情况下两企业利润最少,且与前种情况差距甚大;再次,构建了合作的双寡头企业在不同成本分摊方式下的投资利润函数模型,通过模型仿真分析了不同成本分摊方式对两企业研发投入与合作利润的影响;最后将所有分类情况进行总括对比分析,以期利用实证结果为后续的研究提供理论基础和相应的指导,为企业研发找到最合适的投资方式提供相关建议,切实地提高我国企业的研发能力,促进我国企业的可持续性发展。更多还原

【Abstract】 With the new “the Belt and Road” policy,enterprises are stepping into international market further and further,the R&D cooperation and competition between enterprises are more intense and frequent.And the innovation capability has become the most important driving force and core factor for the enterprises to stand out from the competition and maintain the market share.The research about R&D in our companies started a little later than the abroad ones,and there are still some gaps between us on the R&D overall strength.The past researches on the impact of the technology spillovers,cooperation level and ways is still lack of in-depth analysis.At the same time,most of the previous research used linear R&D probability function,but enterprise R&D probability is more depended on non-linear relationship.In view of the above phenomena and problems,this paper is going to carry on a further research on the basis of the previous,which is expected to establish more accurate models when considering technology spillovers,non-linear R&D success probability function and cost allocation ways in order to provide better suggestions for enterprises’ development.We put forward this research under the background of intensified market competition and urgent demand for R&D innovation.Based on previous research about cooperation or non-cooperation and with technology spillover or without spillovers,this paper conducts a systematic study on whether the competitive duopoly takes cooperation and if the spillovers are taken into to account through model construction and the numerical simulation analysis,which includes monopoly business’ s comparison between single-stage and two-stage decision making,duopoly business’ s comparison between cooperative R&D and non-cooperative R&D in product competition market when considering about spillovers,different modes of cost-sharing in duopoly R&D cooperation and a comparative profits analysis under cooperation or non-cooperation situation.And the simulations shows that non-cooperation duopoly business would get the best benefits and cooperative duopolies would get more when choosing cost reduction allocation mode.Firstly,this paper designs the whole writing ideas and structure of the article.Using theory to build the model,the first part’s writing ideas is divided into the following aspects: considering the impact of one-stage and two-stage R&D investment on the profits of the enterprise under the monopoly condition.Setting up model and simulation parameters lays the foundation for the follow-up modeling and simulation analysis.Secondly,according to the theory and the previous research,this paper ’ s model is combined with the technology spillover factor and the non-linear probability function.And the model is divided into four specific parts,which are constructed and simulated respectively.It can be seen from the simulation results thatthe non-cooperative duopoly business in the case of non-technical spillovers will make the largest market profits respectively.And the two companies will get the lest profits when they choose to invest R&D respectively and use the spillover technology from the other competitor,and the profit gap is enormous compared with the former situation.Thirdly,in order to carry on a further comparative analysis,this paper constructs the enterprise investment profit function models under different cost allocation mode of cooperative duopoly enterprises.And through simulation analysis,the influence of the different cost allocation mode to the R&D investment and the cooperation profits can be obtained.Finally,all the classification cases of comparative analysis are compared with an expect to provide theoretical basis for the follow-up research and give the corresponding guidance and advice for enterprise R&D investment decision making by empirical results.更多还原
