随着新能源汽车自动化程度不断提高,各系统之间耦合造成的故障急剧增加,传统的安全分析方法已无法满足当前汽车复杂系统的危险性分析要求。针对新能源汽车突然失控事故存在的高危性、复杂多样的问题,提出一种基于STPA与模糊BN的新能源汽车安全性分析方法。首先,运用系统理论过程分析方法(STPA)分析新能源汽车突然失控事故,得出系统级事故及危险,构建控制反馈回路,并识别不安全控制行为;接着,根据STPA分析结果构建模糊BN,通过GeNIe软件训练数据,可视化模糊BN,得到基本事件的发生概率,并由试验仿真得出蓄电池及储能系统、电机电控和整车控制器的后验概率分别为0.70、0.17和0.16。结果表明,所提方法能有效识别系统潜在危险,发现系统薄弱环节,可为提高系统可靠性提供依据。

全国统一大市场建设与共同富裕:基于地区市场分割视角

共同富裕是社会主义的本质要求,是现阶段全党工作的重中之重。构建全国统一大市场是实现全体人民共同富裕的基础。而在我国渐进式改革的过程中催生的地区市场分割导致国内市场难以实现一体化,人群、城乡及地区间收入差距扩大,使共同富裕失去了物质基础。因此,从地区市场分割视角探究全国统一大市场建设的共同富裕效应具有重要意义。利用2006—2022年我国30个省份的面板数据,借助系统GMM方法和中介效应模型实证考察地区市场分割对共同富裕的影响效应及其地区异质性,并进一步分析其作用机制。研究发现:地区市场分割对共同富裕产生显著的负向效应,明显抑制我国共同富裕水平的提升,这一结论经过稳健性检验后仍然成立。从市场分割细分类型来看,商品市场分割、劳动力市场分割与资本市场分割均对共同富裕产生显著的抑制作用,其中劳动力市场分割的抑制作用最大,其次是商品市场分割,资本市场分割相对较小。地区异质性分析表明,相比东部和中部地区,西部地区市场分割对共同富裕的负向效应最大,且不同类型市场分割对共同富裕的影响也存在明显的地区异质性,其中东部地区共同富裕水平的提升主要受商品市场分割的制约;中部地区共同富裕水平的提升主要受劳动力市场和资本市场分割的制约;不同类型市场分割都不利于西部地区共同富裕水平的提升。机制检验结果表明,地区市场分割主要通过阻碍产业结构升级、加重要素价格扭曲、加剧环境污染和降低财政可持续,对共同富裕水平的提升产生抑制作用。基于此,加快推进全国统一大市场建设,打破商品市场、劳动力市场与资本市场分割,充分发挥市场机制配置要素资源的决定性作用,强化地区间分工与协作,推动区域协调发展,助力共同富裕的实现。
