Economy, environment, and safety are three important components of sustainable transport. This paper proposes a productivity measurement standard that comprehensively considers economic growth, environmental impact, and safety issues, namely sustainable total factor productivity (STFP). We measure the growth rate of STFP in transport sector of OECD countries in terms of Malmquist-Luenberger productivity index by applying data envelopment analysis (DEA). It is found that the growth rate of total factor productivity in transport sector can be overestimated if safety is ignored. In addition, we discuss the influence of socio-economic factors on the measurement results, finding that there exists a threshold on the impact of environmental regulation intensity on the growth of STFP in transport. That is, STFP increases with environmental regulation intensity if it is smaller than 0.247, while STFP decreases if it is larger than 0.247.
经济、环境和安全是可持续交通的三个重要组成部分。本文提出了一个综合考虑经济增长、环境影响和安全问题的生产力衡量标准，即可持续全要素生产率（STFP）。我们利用数据包络分析（DEA），根据 Malmquist-Luenberger 生产力指数来衡量经合组织国家运输部门的 STFP 增长率。研究结果表明，如果忽略安全问题，运输部门全要素生产率的增长率可能会被高估。此外，我们还讨论了社会经济因素对衡量结果的影响，发现环境监管强度对运输部门 STFP 增长的影响存在一个阈值。也就是说，如果环境监管强度小于 0.247，那么 STFP 会随着环境监管强度的增加而增加，而如果环境监管强度大于 0.247，那么 STFP 会随着环境监管强度的增加而减少。
