中文摘要：

中国的收入差距与刑事犯罪存在着内在的逻辑关系，且前者对后者的影响具有非线性特征。从刑事案件规模来看，收入差距对刑事犯罪的影响具有“U”型曲线特征，即适度的收入差距将降低刑事犯罪率，而其进一步扩大则将带来后者的攀升；从刑事案件结构来看，收入差距显著地诱发了暴力型案件中的凶杀罪和伤害罪，以及财产型案件中的盗窃罪，且尤以盗窃案件所受到的影响为明显。缓和、消除收入阶层之间的矛盾，进而优化生存和生产环境，应以形成合理有序的收入分配格局为前提，而促进农民增收是关键。

From the view of offence scale, in- come gap influences criminal ofl＇ence with curve character of ＂ U＂ shape, which demonstrates that moderate income gap will lower the criminal offence rate, while its turther enlarge will raise the rate. From the view of offence structure, income gap obviously induces violence offence including murder and hurt cases, property ofl＇ence including theft case which is much more influenced. To ease and eliminate the conflicts between difl＇erent income groups, and to optimize the living and produ- cing environment, forming the rational and well - organized income - distribution structure is the premise, and finally im- proving the farmers＂ income is the key issue.
