毒品犯罪与次生犯罪共生关系:以华北沿海T市为例

Exploring Colocalization Relationship between Drug-related Crimes and Secondary Crimes:Take T City on the Coast of North China as an Example

毒品犯罪具有易诱发暴力犯罪的特点,毒品犯罪对其次生犯罪的引发作用是该领域的重要研究内容之一。引入经济学领域基于距离测度的产业聚集度DO指数(DO index),以华北沿海T市2018—2019年的毒品犯罪和其次生犯罪作为研究对象,将两类犯罪共生关系数值化。研究表明:毒品犯罪与四类次生犯罪(抢劫罪、强奸罪、危险驾驶罪、故意杀人罪)在空间上呈现出小尺度共聚关系,共聚程度随距离变化在理性选择理论的作用下多为倒U形关系。毒品犯罪与故意伤害罪在空间上为随机分布关系,该关系受当地民风民俗与毒品特殊药理性影响。作为对日常活动理论空间视角的补充,警方可加强毒品犯罪发案0.48 km范围内相关人员的管控,以达到对与其具有共聚关系的次生犯罪的有效控制。

Drug crimes have the characteristic of easily inducing violent crimes,and the triggering effect of drug crimes on their secondary crimes is one of the important research contents in this field.Introducing the DO index of industrial agglomeration degree based on distance measurement in the field of economics,focusing on drug crimes and their secondary crimes in a coastal T City from^(2)018 to 2019,and the symbiotic relationship between the two types of crimes was digitized.Research has shown that drug crimes and four types of secondary crimes(robbery,rape,dangerous driving,and intentional homicide)exhibit small-scale co-occurrence in space,and the degree of co-occurrence varies with distance.Under the influence of rational choice theory,it is mostly an inverted U-shaped relationship.The relationship between drug crimes and intentional harm crimes is randomly distributed in space,which is influenced by local customs and the special pharmacological properties of drugs.As a supplement to the theoretical spatial perspective of daily activities,the police can strengthen the control of relevant personnel within a 0.48 km radius of drug crimes,so as to achieve effective control over secondary crimes that have a common relationship with them.
