网络效应、市场结构及技术进步——基于异质性偏好视角的分析Network Effect,Market Structure and Technology Progress:Analysis Based on Heterogeneous Preference
彭恒文,杜运苏
摘要(Abstract)：
技术进步包括技术创新和技术更新,基于异质性偏好视角的网络效应下技术创新模型仅仅对比了仅有旧技术及新旧技术并存这两种状态,只是研究了技术创新,而尚未包括从新旧技术并存转为仅有新技术这一技术更新过程。基于异质性偏好的视角,本文考察了网络效应下消费者和厂商在技术创新、技术更新两阶段中的技术选择,在此基础上研究了竞争对于技术创新及技术更新的作用,并针对中国邮电通信业进行了实证分析。基本的结论在于,异质性偏好和网络效应共存条件下竞争能够增强技术创新、技术更新的动力,有助于技术进步,而相应的实证分析也证明了这一点。
