Abstract: The importance of afforested area in environmental protection was emphasized in the 12th Five Year Period. Therefore, we first synthetically assess the afforested efficiency by non-oriented Network SBM model. The overall process is divided into two stages, and PM2.5, NO x , and SO 2 are viewed as the linkage between two stages. Moreover, the afforested area is used as the final output in the second stage. According to the empirical results, the energy efficiency is higher than the afforested efficiency, and the low overall efficiency mainly due to the bad performance of afforested efficiency. The average afforested efficiency score was less than 0.42 in these five years, indicating that although the average afforestation area increased gradually, the afforestation efficiency did not improve significantly. Most provinces should take effective measures to control the emissions of PM2.5, NO x , and SO 2 and gradually improve the afforested area.
