公司创业投资是成熟产业公司进行外部探索与学习的新兴战略手段,创始人CEO的个人特质则与公司创业投资高收益与高风险并存等特点相契合。基于高层梯队理论,利用2009—2020年创业板上市公司的数据,探讨了创始人CEO对公司创业投资的影响。研究发现,创始人CEO有助于促进企业发起公司创业投资。进一步分析发现,创始人CEO的组织认同、冒险倾向和社会资源等特质发挥了调节作用。其中:在组织认同方面,当外部大股东治理更弱和产品市场竞争程度更低时,创始人CEO对公司创业投资的提升作用更强;在冒险倾向方面,当企业环境不确定性更高、女性董事比例更高时,创始人CEO更能发挥对公司创业投资的促进作用;在社会资源方面,当企业接受过私募与风险投资时,创始人CEO更能推动公司创业投资的开展。此外,创始人CEO能够有效引导独立创投单元的设立与运营,推动创投单元更多地投资于早期新创企业,促进创投单元参与联合投资。因此,企业应弘扬企业家精神,制定有效促进公司创业投资的措施,促进新创企业科技成果的转化,助力经济高质量发展。

Zhang and collaborators [1] demonstrated that bees of the genus Ctenoplectra collect oil from the newly reported oilreward orchids of the genera Dendrobium and Galeola in Asia, and that the majority of the bees that carry out this act and pollinate the orchids are male. These are new discoveries with significant implications for biodiversity conservation.

Dynamic plugging regulating strategy of pipeline robot based on reinforcement learning

引用

Petroleum Science 2024年第1期21卷 597-608页

作者： Xing-Yuan Miao hong Zhao College of Mechanical and Transportation Engineering China University of PetroleumBeijing102249China

Pipeline isolation plugging robot (PIPR) is an important tool in pipeline maintenance operation. During the plugging process, the violent vibration will occur by the flow field, which can cause serious damage to the pipeline and PIPR. In this paper, we propose a dynamic regulating strategy to reduce the plugging-induced vibration by regulating the spoiler angle and plugging velocity. Firstly, the dynamic plugging simulation and experiment are performed to study the flow field changes during dynamic plugging. And the pressure difference is proposed to evaluate the degree of flow field vibration. Secondly, the mathematical models of pressure difference with plugging states and spoiler angles are established based on the extreme learning machine (ELM) optimized by improved sparrow search algorithm (ISSA). Finally, a modified Q-learning algorithm based on simulated annealing is applied to determine the optimal strategy for the spoiler angle and plugging velocity in real time. The results show that the proposed method can reduce the plugging-induced vibration by 19.9% and 32.7% on average, compared with single-regulating methods. This study can effectively ensure the stability of the plugging process.
