中国三大海洋经济圈海洋经济发展区域差异与分布动态及影响因素

考察中国海洋三大经济圈海洋经济发展区域差异,探究其分布动态演进规律,识别其空间非均衡的影响因素及空间溢出效应,为“十四五”期间优化海洋经济发展空间布局、推动区域海洋经济协同均衡发展提供决策参考。利用Dagum基尼系数及其分解方法考察三大海洋经济圈海洋经济发展区域相对差异的程度、来源及演变态势,在此基础上,进一步应用Kernel密度估计方法刻画其绝对差异的分布动态演进过程,并将空间效应纳入研究框架,应用空间计量分析方法识别海洋经济发展空间非均衡的影响因素及空间溢出效应。研究发现：三大海洋经济圈海洋经济发展均呈现稳定上升态势,但三者之间存在显著的分级现象;三大海洋经济圈空间非均衡程度显著,超变密度是造成三大海洋经济圈整体区域差异的主要来源;三大海洋经济圈海洋经济发展水平“极化效应”显著,呈现不同极化特征和分布延展性;三大海洋经济圈海洋经济发展存在显著的空间依赖性,总体表现为空间正相关。     

风门开闭动态过程对矿井风流影响规律研究*

为探究风门开闭动态过程对矿井风流的影响规律,采用数值模拟方法,得出风门开启角度对于巷道内流场变化及测点风速波动的影响及其规律,结合实验验证测点风速波动规律,并分析风门开启角度与第1次峰值出现时间、异常风速波动时长、风速波动幅值3个波动特征之间的关系。研究结果表明:风门开启后,风门所在巷道及其关联巷道流场产生剧烈波动;风门关闭后,波动影响也不会立即消失;风门开闭动态过程中,所有测点的风速皆呈现先升后降或先降后升的波动规律,随后进入震荡过程,最后震荡逐渐减小至正常风速波动范围内,其中风门所在巷道的测点风速会在震荡过程中产生风速方向反转现象;经对比分析,风门前的测点风速波动特征更好反映风门开启角度,二者呈正相关性。     

智能化驱动下矿工变革支持行为的代际差异研究*

为促进煤矿智能化变革,提升安全生产水平,结合价值观匹配理论,建立安全价值观匹配、工作满意度和矿工变革支持行为的理论假设模型。基于567名智能化矿山矿工的有效数据,应用结构方程模型和Bootstrap方法进行路径检验及中介效应检验,并采用多群组分析方法检验代际差异的分类调节作用。研究结果表明:内部安全理念匹配和外部社会责任匹配均对矿工变革支持行为有显著正向影响;工作满意度对矿工变革支持行为具有显著正向影响,同时在安全价值观匹配与矿工变革支持行为的关系中起中介作用;内部安全理念匹配和外部社会责任匹配对新生代矿工变革支持行为的影响效用均大于老一代矿工。提高矿工与组织的安全价值观匹配程度和工作满意度,减少老一代矿工的变革阻力,有利智能化矿山建设。
