Are Chinese transport policies effective? A new perspective from direct pollution rebound effect, and empirical evidence from road transport sector

TL;DR

This study introduces a new pollution rebound effect concept and empirically assesses Chinese transport policies' effectiveness in reducing air pollution, finding evidence that policies have been effective in lowering emissions in the road transport sector.

Contribution

It proposes the pollution rebound effect (PRE) concept and empirically measures its impact on policy effectiveness in China's transport sector from 1986 to 2014.

Findings

Short-term direct air PRE is -1.4105.

Long-term direct air PRE is -1.246.

Chinese transport policies effectively reduce emissions.

Abstract

The air pollution has become a serious challenge in China. Emissions from motor vehicles have been found as one main source of air pollution. Although the Chinese government has taken numerous policies to mitigate the harmful emissions from road transport sector, it is still uncertain for both policy makers and researchers to know to what extent the policies are effective in the short and long terms. Inspired by the concept and empirical results from current literature on energy rebound effect (ERE), we first propose a new concept of pollution rebound effect (PRE). Then, we estimate direct air PRE as a measure for the effectiveness of the policies of reducing air pollution from transport sector based on time-series data from the period 1986-2014. We find that the short-term direct air PRE is -1.4105, and the corresponding long-run PRE is -1.246. The negative results indicate that the direct air PRE does not exist in road passenger transport sector in China, either in the short term or in the long term during the period 1986-2014. This implies that the Chinese transport policies are effective in terms of harmful emissions reduction in the transport sector. This research, to the best of our knowledge, is the first attempt to quantify the effectiveness of the transport policies in the transitional China.
