摘要

雲林縣為乃農業發展之重要縣市，務農機具使用普及，但其防護設施不足，導致竊盜案件層出不窮。因應農機具竊盜發生率的逐漸攀升，內政部警政署函頒「試辦農漁牧機具防竊刻碼計畫」，藉以減少失竊率。本研究主要透過雲林縣警察局受理民眾針對農機具報案後，就該案件類型輸入刑案紀錄表之資料，以差異中之差異法將實施政策後之受政策實施影響族群視為實驗組，未受政策實施影響之族群視為對照組，藉此釐清「農機具刻碼」政策之效果。研究結果顯示，在該政策執行下，雲林縣轄內的農機具失竊情形確實有顯著性的降低，這也表示該項政策的執行確實有助於農漁民的生計產生效益，且有利於警察在查緝贓物時「查贓緝犯、緝犯追贓」。相對的以該種「刻碼」印記的方式標示在物件財產上，更有助於竊盜犯罪的犯罪意圖降低。

To cope with the increasing loss rate of agricultural machinery and tools, the Taiwanese government implemented the program in 2009. The objective of this program is to reduce the loss rate of farmers' agricultural machinery and tools, and consequently sustain the wellbeing of farmers. The primary aim of this study is to make possible contributions to this policy issue by using the administrative data released by the police stations in Yunlin county of Taiwan to empirically assess whether this program achieves it policy goals.Our empirical analysis relies on the approach commonly used in the program evaluation literature. The difference-in-differences (DiD) method was implemented to isolate the net effect of the program. The findings suggest good prospects for the program. The implementation of the program successfully reduces the loss rate of agricultural machinery and tools in Yunlin County. A more aggressive policy implication can be inferred from this study. Instead of using extensive policy manpower to investigate potential crime, the agricultural engraved brand system can also achieve the policy goals.
