重大责任事故罪是一种比较多发的危害公共安全罪,给国家和人民的利益造成了重大的损失。目前学界对于重大责任事故罪的研究主要集中理论方面，而本文则是以统计分析重大责任事故罪的犯罪主体、客观行为及结果、量刑为目的，以2014年度已判决的377个案件为对象展开的实证研究。本文统计分析了犯罪主体性别、年龄、文化程度、籍贯、职位，犯罪发生的时间、地点、行业、行为和危害结果，罪犯的刑种、刑期、刑罚执行方式和量刑情节等信息，从犯罪主体、犯罪客观方面以及定罪量刑三个方面，对重大责任事故罪展开了研究。全文分为5章，包括研究方案、犯罪主体的情况、犯罪客观方面的情况、量刑情况、研究结论的总结与启示，约42000字。 为了实现重大责任事故罪的预防和惩治，我们有必要加强对员工职业技能和安全生产方面的教育培训，以改变犯罪主体低学历化、基层化的现状；此外，对建筑业、采矿业等事故多发的行业还应才取特殊的监管措施。我们还应正视单位在犯罪中所起的作用，增设单位犯罪来扩大本罪的犯罪主体；在借鉴国外立法例和吸收我国有关禁止令的规定的基础上增设资格刑、罚金刑，弥补本罪处罚措施单调的不足。同时，实践中应该准确把握事故调查与刑事侦查的关系，做好行政与司法的衔接工作；做到对法定和酌定从轻处罚情节的准确把握，解决从宽幅度过大、量刑过于轻缓化这一现状。
