Modeling pollution control and performance in China's provinces

The paper constructs a pollution control performance (PCP) evaluation model by introducing the norm of n-dimensional space. The PCP of 30 Chinese provinces for the period of 2003–2008 is evaluated based on the model and the factors influencing China's pollution control are further examined. It is found that: (1) China's PCP has improved rapidly but there is a large regional imbalance with the PCP of Eastern China being much better than that of Central and Western China; (2) to improve the level of China's PCP, government policies should consider industrial structure adjustment, restricting industry entries and increased investment in pollution abatement and R&D.

► A pollution control performance (PCP) evaluation model of n-dimensional space is constructed. ► China's PCP is still low and displays a tendency for regional imbalance. ► Structural adjustments need better integrate with environmental protection. ► Economic development significantly promotes the level of regional PCP.
