多元化為二十一世紀公共行政的重要課題之一，而既有研究也指出多元化足 以揚升組織績效。然而，基於警察勤務深具「危險性、機動性、辛勞性」，國內 警察機關的女警比例相當低落。本研究以2001年至2009年臺灣省各縣（市）警 察機關的相關數據進行實證分析，探究女警比例與犯罪發生率之間的相關性。追 蹤資料模型的分析結果顯示，針對「刑案發生率」、「竊盜案發生率」與「暴力 犯罪發生率」等三種不同的犯罪類型，各縣（市）犯罪發生率的情況皆未因為女 警比例提高而增加，相反地，女警比例與犯罪發生率之間呈現顯著的負向關係， 顯見對警察機關而言，性別多元化對組織績效同樣有其正面效益。

The gender diversity in Taiwan’s police departments is extremely unbalanced due to the presumption of risk, mobility and toil of police’s duty which generally believed that the male is more competent than females. This study analyzes the relation between the policewomen proportion and criminal rate empirically by gathering relevant variables and data of 21 counties in Taiwan during the period 2001 to 2009. According to the panel data model, the policewomen proportion has remarkable positive relevance with the decrease of crimes in a county, including the criminal cases, larceny and violent crimes. Hence this study will be a practical reference to promote gender diversity in public services in Taiwan.
