研发投入与企业绩效的非平衡统计关系研究

Research on Non-equilibrium Statistical Relationship between R&D Investment and Enterprise Performance

研发创新是企业生成核心竞争力的关键。研发投入与企业绩效之间的关系一直是学者研究的重要内容。将非平衡统计理论及朗之万方程推广运用到经济学领域,建立该领域的广义朗之万方程,求解出企业研发投入与其绩效的统计关系。结果表明企业绩效与研发投入呈非线性关系,蕴含一定的客观统计规律。

R&D innovation is the key of the core competitiveness for enterprises.The relationship between R&D investment and enterprise performance has been a major issue for economists. This paper applies the non-equilibrium statistical theory and Langevin equation to economic sphere, and establishes the generalized Langevin equation in the field of economics to solve the statistical relationship between R&D and the performance. The statistical relationship indicates that enterprise performance and R&D investment are nonlinear,which contains certain non-equilibrium statistical laws.
