| Summary: | 碩士 === 國立臺灣大學 === 經濟學研究所 === 104 === This study employed the ordinary least squares (OLS) method to perform multiple regression analysis and explore the influence of economic climate, policing, and population structure on the crime rate. First, a review of the criminology and economics literature was conducted to explore the mutual relationship between the economic climate, policing, and population structure of a society and its crime rates. To explore the problem of crime rates and economic pressure, this study considered the “population ratio based on monthly income from major jobs of employees” as the main explanatory indicator and predicted that this variable would clearly show how the population groups based on monthly income influenced the crime rate. Research results show that crime rate has a negative relationship with the economy. The proportion of employees with monthly income of less than NT$ 15,000 has a positive correlation with crime rate. An increase in police spending can effectively check criminal activity and has a negative correlation with crime rate. With regard to demographic variables, compared to the population aged 65 years and above, an increase in proportion of the population aged 25–39 years shows a significant positive influence on the crime rate, indicating that the youth population is a main factor in the age structure of crime in Taiwan.
