The concept of congestion, which is mainly applied in economics, refers to a situation where inputs are overinvested.
Many studies have focused on congestion measurement by means of data envelopment analysis (DEA).
However, most of the previous investigations only considered the framework of desirable outputs.
In fact, firms in the real world unavoidably generate undesirable outputs (such as pollutants or wastes) along with desirable outputs.
Therefore, a new scheme is required for measuring congestion in the simultaneous presence of both desirable and undesirable outputs.
This paper develops a nonradial efficiency measure for including undesirable outputs into the environmental performance.
Based on the proposed model, a new definition and a new approach are presented to deal with congestion in the simultaneous presence of desirable and undesirable outputs.
Then, this paper uses the presented method to study the pollutants (waste gas emission and waste discharge) of 31 administrative regions of China.
The finding indicates that 7 industries pay attention to the reduction of their pollutants accompanying improvement of their commercial targets.
Consequently, they do not show congestion in any input.
