| Summary: | 碩士 === 國立中山大學 === 公共事務管理研究所 === 97 === This research use three phase stage- Data Envelopment Analysis to examine 49 police stations, 10 police precincts of Kaohsiung City Government Police Bureau(KCGPB) from 2003 to 2007 regarding the statistical data of KCGPB. In phase one, using SBM-DEA method analyses the management efficiency and the amount of input and output variable. In second phase, using SFA regression analyses to probe into the environmental variable influencing degree to each police station of KCGPB. In addition, it takes account of the environmental effect and the random interference effect to improve input and output variable. Finally, by way of DEA and Malmguist productivity index, it can measure the relative effects and the productivity change situations between each police station.
The model result shows that SBM-DEA can weigh input difference and total output difference at the same time, by the way of using ratio adjustment, it can determine the really administration efficiency of every police station. According to phase one analysis results, 245 DMUs efficiency values are below 1, it is almost 100% of all the DMUs efficiency values and shows that still have very big improvement space. By the regression analysis of phase 2, we know that the environmental parameter will exert an huge influence on input and output difference, in which the most influence is the environmental parameters of violence crime on duty-costs, public services, and real-time solution of criminal cases. After adjustment every DMUs, there are 245 efficiency values getting higher. The amount of getting higher efficiency value is almost 100% of all the DMUs. After adjustment environmental parameter, about 96% change in rank, with 24 DMUs advancement in rank, 23 DMUs degeneracy in rank, and only 2 DMUs unchanged. It shows that 24 DMUs work in unwell environment before adjustment, and 23 DMUs work in well environment before adjustment. It also shows that each police station still exist difference in working environment. Although the whole efficiency of thw police stations represent is not bad, but it still has large improvement space. Furthermore, according to Malmquist model efficiency index analysis from 2003 to 2007 data of all police stations shows that the total productivity element in Sanming First Precinct, Sanming Second Precinct, Cianjhen Precinct, Gushan Precinct, Yancheng Precinct, Zuoying Precinct and Siaogang Precinct are higher than 1, it can attributes to the increasing of technology; Sinsing and Lingya Precincts are lesser than 1, it can attributes to the decreasing of technology efficiency.
