企业既可以选择降低成本的创新,也可以选择提高质量的创新。研究发现:只有当成本降低的程度相对于质量提高的程度足够大时,或者成本降低的程度相对于质量提高的程度处于适度范围时,企业在技术创新方向的选择上才会存在一个企业选择进行降低成本的创新活动而另一个企业则选择提高质量的创新活动的纯策略纳什均衡;只有当成本降低的程度相对于质量提高的程度处于另外一种适度范围时,企业在技术创新方向的选择上才会存在两个企业同时选择降低成本的创新活动的纯策略纳什均衡;只有当成本降低的程度相对于质量提高的程度足够小时,企业在技术创新方向的选择上才会存在两个企业同时选择提高质量的创新活动的纯策略纳什均衡。最后,基于模型分析提出了对"中国制造"升级到"中国创造"具有启迪性的政策建议。
Enterprises can choose either the technological innovation aimed at reducing the cost or the technological innovation aimed at improving the quality. It is found by this study that only when the degree of cost-reducing relative to that of quality-improving is large enough or moderate, will the pure strategy Nash equilibrium be found in choosing the techonogical innovation direction by enter- prises, in that case one may choose the cost-reducing innovation while the other may adopt the quali- ty-improving innovation. Secondly, only when the degree of cost-reducing relative to that of quali- ty-improving falls into another moderate range, will the pure strategy Nash equilibrium be found in choosing the techonogical innovation direction by enterprises, in that case two of them choose the cost-reducing innovation at the same time. Thirdly, only when the degree of cost-reducing relative to that of quality-improving is small enough, will the pure strategy Nash equilibrium be found in choos- ing the techonogical innovation direction by enterprises, in that case two of them choose the quali- ty-improving innovation at the same time. Finally, it puts forth some enlightening policy suggestions for upgrading "made in China" to "created in China" based on the model analysis.
