基于外资渗透和部分私有化的混合多寡头研发投入研究

Research on R D Investment of Mixed Oligopoly with Foreign Penetration and Partial Privatization

摘要:

考虑到含有部分私有化的公共企业、纯私营企业、合资企业的混合三寡头市场竞争,构建了混合三寡头的两阶段博弈模型,得出了企业在研发投资时各个变量的均衡解以及最优解,并分析了私有化程度、合资企业的国内控股比例对研发投入、社会福利的影响。结果表明私有化程度的提高将会使公共企业减少研发投入,私营企业和合资企业将会增加投入；合资企业的国内控股比例的增加将会提高最优社会福利。

Abstract:

Considering the mixed triopoly market competition containing one public firm with partial privatization, one pure private firm and one joint venture with domestic and foreign stockholders, this paper constructs a two-stage game model based on mixed triopoly, and obtains the equilibrium solution and optimal solution of each variable when firms invest in R D. The impact of the degree of privatization and domestic stockholding of joint venture on the R D investment and social welfare are analyzed. The result shows that the R D investment of public firm will decrease and the R D investment of private firm and joint venture will increase along with an increasing the degree of privatization, an increase in domestic stockholding of joint venture will improve optimal social welfare.
