The purpose of this paper is to construct a method to estimate TFP in network industries, and to estimate TFPs in industries : video-game, information processing, cellular phone, and LP gas distribution industries. Generally, estimating TFP in these industries means means estimating TFP of production devices, such as game machine, computers, cellular phone terminals. Here, the productivity of a total system involving not only hardware but software. First, a theoretical model to estimate TFP is constructed, which claims that we can estimate system outputs employing changes of software prices, sales of software, and number of hardware. This is a way to estimate outputs observing induced demand for inputs. Second, TFP growth in those industries showed surprising slow downs for recent decade in Japan. Even the video-game industries indicated negative value of TFP growth rate for 2001, which is a result of decrease of sales of game-soft in spite of penetration of game machine and decrease of game-soft. Also, recently in the cellular phone industries, the increase of traffic is less than increase of cellular phone, which results in negative TFP. Third, technical efficiency is estimated in LP gas distribution.

本文的目的是构建一个估算网络行业TFP的方法，并估算视频游戏、信息处理、手机和液化石油气分销行业的TFP。一般来说，估计这些行业的TFP就是估计生产设备的TFP，比如游戏机、电脑、手机终端。这里指的是不仅包括硬件而且包括软件的整个系统的生产率。首先，构建了一个估算全要素生产率的理论模型，该模型认为我们可以利用软件价格、软件销售额和硬件数量的变化来估算系统产出。这是一种通过观察对投入的诱导需求来估计产出的方法。其次，近十年来，日本这些行业的全要素生产率增长出现了令人惊讶的放缓。即使是电子游戏行业，2001年的TFP增长率也出现了负值，这是由于游戏机的普及和游戏软件的减少，但游戏软件的销量却减少了。此外，最近在移动电话行业，流量的增长小于移动电话的增长，这导致负TFP。第三，估算了液化石油气配气的技术效率。
