Abstract: This paper calculates the efficiency of land-based pollution governmentin coastal areas and analyzes the differences of time and space.It uses Data Envelopment Analysis and Malmquist index and it is based on the panel data of coastal provinces between 2003 and 2012.Besides, it investigates the factors that affect efficiency.Through the paper we can get several conclusions:firstly, the Total Factor Productivity of land-based pollution government between 2003 and 2012 is going down slightly mainly because of the drop of techch; secondly, the values of tfpch between different provinces are different as a result of different techch; thirdly, the efficiency of land-based pollution government in Circum-Bohai Sea Economic Zone is low and decreases significantly after 2008; fourthly, R &D investment and environmental protection investment will promote the reduction of land-based pollution.Besides, the scale of industry has significant positive effect on land-based pollution.
