京津冀协同发展下河北省产业升级动态多维博弈研究

Study on Multi-Dimensional Dynamic Game About Industries Innovation in Hebei Province Under Beijing-Tianjin-Hebei Synergetic Development

京津冀协同发展下,河北省在产业承接中取得了重大成果,但产业优化升级依然是首要任务。根据多维博弈理论,以河北省著名钢铁企业为例分析,构建具有需求替代性新旧产品进行产量—价格策略的博弈模型,求解均衡并进行实证对比。分析表明:尾随企业未必存在后动优势;行业中两个企业单独对产品进行博弈劣于联合进行二维博弈的均衡策略,在产业创新、升级中,企业一定要合作而不是单纯竞争。

Under Beijing-Tianjin-Hebei synergetic development,Hebei province in the industry undertaking has made significant achievement, but the industrial optimization and upgrading is still the primary task. In this paper, based on the theory of multidimensional game, taking the famous iron and steel enterprises in Hebei province as an example, this paper constructs a game model of output price strategy with demand substitution of old and new products. The analysis shows that the trailing enterprise may not exist advantage, the strategy of two enterprise compare the products by them self is worse than the strategy of combination produce, in the industrial innovation and upgrading, enterprises must cooperation rather than competition.
