BLP模型发展及其在产业组织应用综述

产业组织理论问题的实证研究方面,以往简约式方法侧重于分析变量之间的因果关系,难以辨别问题背后的变化机理,从而影响其在政策评估、福利分析中的应用。近年来,随着新实证产业组织研究范式的兴起,结构模型的研究受到国内外学者的广泛关注,并成为新实证产业组织问题研究的前沿方法。BLP模型基于供需关系估计需求和成本参数,估计得到的结构参数更加贴近现实,能够进行均衡及福利分析,合理地评估产业政策,其应用是新实证产业组织研究的焦点问题。通过全面细致地解释BLP模型的原理、方法、发展脉络和研究现状,分析其特点和优势,梳理了BLP模型的应用领域,为产业组织理论问题的实证研究提供方法依据。最后,根据现有研究提出模型不足以及未来的研究方向。

A Literature Review on the Development of BLP Model and Its Application in Industrial Organization

Recently,with the rise of new empirical industrial organization research,the study of structural model has been widely concerned by scholars,and has become the frontier method of empirical industrial organization research.BLP model is based on the relationship between supply and demand to estimate demand function parameters and the marginal cost function,it is used to estimate the structural parameters more realistic,and to analyze the equilibrium and the welfare,and it is also able to evaluate industrial policies more reasonably,so as to get more practical policy suggestions.The research and application of BLP model are the focus of the research of new empirical industrial organizations.This paper comprehensively and carefully explains the principle,method,advantages and limitations of BLP model,sorts out its development context and research status,analyzes the characteristics and advantages of BLP model,introduces the application of BLP model in industrial organization,and provides the method basis for the empirical research on industrial organization.Finally,according to the existing research,the deficiencies and future research directions are proposed.
