This study mainly uses Meta-Frontier to estimate the efficiency of Taiwan's police production technology. The empirical point out that the inefficiency of Taiwan's policing management is the main source of inefficiency in production technology. The six capitals' production technology efficiency values CRS, VRS and SE are superior to the county and city policing production technology efficiency values in the group and common boundary. The TGR value of the common boundary during the whole period is 0.9525, which means that there is 4.745% optimization space in Taiwan's police administration; the TGR of Liudu is 0.8835, which means that the gap between the six capitals and the Meta-Frontier is larger than that of the whole period.
