The Malmquist Productivity Index and Plant Capacity Utilization
提出一种新的Malmquist生产率指数分解方法，将生产率变化分解为技术效率变化、工厂产能利用率变化和前沿移动，为衡量产能利用率变化对生产率的影响提供了替代方案。
A new decomposition of the Malmquist productivity index is proposed to account for changes in plant capacity utilization. Using a primal, non‐parametric specification of technology, the Malmquist index is decomposed into technical efficiency change, variations in plant capacity utilization and frontier shifts. It provides an alternative to the available methods of incorporating capacity utilization changes into measures of productivity change. Such measures are based on parametric (and, in many cases, dual) technology specifications; moreover, they typically do not allow for technical inefficiency. JEL Classification C 61; D 24
