文献中提出了几种测量生产力的技术。在考虑生产单位的低效率的同时，我们提供了衡量全要素生产率的替代方法的方法学比较。本文评估了政府补贴和对外贸易等非预期政策结果的影响。本文采用面板数据对日本46个地区的木材生产力进行了实证分析。结果表明，尽管平均趋势相似，但这两种技术之间的生产率存在很大差异。我们发现补贴阻碍了竞争，因为政府愿意用补贴拯救亏损的公司，而不是让它倒闭。相反，贸易被证明对生产率有积极影响。
Several techniques have been proposed in the literature to measure productivity. While allowing for inefficiency of the production unit, we provide a methodological comparison of alternative approaches to measure total factor productivity. This article evaluates the effects of unintended policy outcomes such as government subsidies and foreign trade. Empirically, we analyse the forest productivity of timber in Japan by using panel data on 46 regions. The results suggest substantial variation in productivity between these two techniques although average trends are similar. We find that subsidies impede competition since the government is ready to rescue a loss-making firm with subsidies rather than allow it to close. In contrast, trade is shown to have positive effects on productivity.
