中国经济地理概论 闫昊生 孙久文
2021/1/19
关于经济地理学的研究对象和任务，多年来一直是各国经济地理学者探讨的一个理论问题。国外学者认为，经济地理学主要研究包括生产、交换、消费的广义的经济活动，这种研究是在地区基础上或以一定的地区为单位而进行的；不仅研究经济活动的分布，而且联系到经济的空间结构；在联系有关因素时，把地理环境摆在重要地位，着重探讨经济活动和地理环境的关系。
由于环境信息在可验证性方面存在一定问题，偏远的地理位置可能会导致企业管理层在环境信息披露方面的机会主义行为，而股东的监督则可以减少这种机会主义行为的发生。选取2009 ~ 2016年我国制造业上市公司为样本，以监管距离为切入点，探索地理位置、股东监督对环境信息披露的影响。研究结果表明，随着监管距离的增加，国有企业的环境信息披露总量明显下降，非国有企业则相反。而在股东监督较强时，国有企业上述机会主义...
基于脆性熵的群体踩踏事件演变研究
脆性联系熵 复杂系统 系统崩溃 群体踩踏事件
2018/9/26
大规模群体踩踏事件的成因和演化过程成为公共危机管理的研究热点之一。文章利用脆性熵来研究系统崩溃成因及演化。根据人流去向和波动情况的比率来表征事件的同一概率、波动概率和对立概率,并根据其值来计算相应的脆性同一熵、脆性波动熵、脆性对立熵,同时利用燕尾突变级数法求出各种熵在脆性联系熵中的权重用以计算系统的脆性联系熵,表明脆性基元内子系统的熵值在外界干扰过程中不断增加,达到临界熵值而崩溃,致使发生大规模群...

中部地区产业结构高级化测度及效应分析
中部地区 产业结构高级化 偏离—份额法 产业结构高级化效应
2018/6/21
基于劳动生产率，以各次产业的劳动份额作为权重测度中部地区的产业结构高级化，再利用偏离—份额法分析其对经济增长的影响。实证结果显示，中部各省的产业结构高级化趋势基本一致，高级化水平都有所提高，但分别处于工业化已完成和未完成的层次。三次产业的高级化水平存在明显差异，按照第三产业、第二产业和第一产业的顺序递减；从经济总体的视角来看，中部地区的产业结构高级化对其经济增长存在积极影响，但三次产业的结构高级化...
