过去数十年，香港客运的能源消耗迅速增加，2008年占总能源消耗的19.7%。提高能源效率被广泛认为是减少运输部门能源使用的有效途径。然而，由于反弹效应的存在，能源效率提升所带来的预期节能量可能会打折扣。本文采用计量经济模型来估计香港私人客运的直接反弹效应。我们发现，1993-2009年和2002-2009年的直接反弹效应的幅度分别为45%和35%，这表明随着时间的推移，客运的直接反弹效应有下降的趋势。报告亦指出，在评估能源效益措施对减少香港能源使用的影响时，需要考虑直接反弹效应。
Energy consumption by passenger transport in Hong Kong increased rapidly in the past decades and in 2008 it accounted for 19.7% of total energy use. Improving energy efficiency has been widely regarded as an effective way for reducing energy use in the transport sector. However, the expected energy savings from energy efficiency improvement are likely to be discounted due to the existence of rebound effect. This paper employs econometric models to estimate the direct rebound effect for private passenger transport in Hong Kong. We find that the magnitudes of the direct rebound effect are respectively 45% and 35% for 1993–2009 and 2002–2009, which indicates that there was a declining trend in the direct rebound effect for passenger transport over time. It also indicates that the direct rebound effect needs to be taken into consideration in assessing the impact of energy efficiency measures on reducing energy use in Hong Kong.
