畅通要素流通壁垒,推动公共数据作为创新资源向企业流动,鼓励并引导企业利用公共数据实施创新决策和成果转化至关重要。本文以我国各省(自治区/直辖市)陆续开通公共数据开放平台为准自然实验,证实了开放公共数据对企业创新具有促进作用,上述关系以对数据生产要素的资源补给机制和对创新意愿的动力激发机制为双向路径。基于行业性质的细分检验发现,当前释放数据生产要素对实现数字产业化作用明显,但依托产业数字化助力实体经济效果有限。进一步地,本文发现数据传输效率是影响上述关系的关键因素,而现阶段开放文化教育和公共服务性质的数据生产要素效果更佳。与此同时,基于企业既有要素水平的异质性分析发现,对技术、资本等生产要素在位积累性更强的企业而言,上述关系更显著。本文补充了关于数据生产要素实际经济价值的实证证据,为完善数据生产要素流通机制,激励企业释放数据变现价值提供了政策启示。

河东柳氏西眷主支于西魏大统四年(538)西入长安加入关中政权,在所谓关中郡姓群体中,入关初期的河东柳氏西眷无论门第阀阅、乡土根基、部曲势力都相对逊色,其之所以能在家族竞争中脱颖而出,除了关西政权注重功绩的政策环境、柳氏西眷文质兼备的家族特质外,柳虬兄弟的守望相助以及核心人物柳庆的卓越才具也是不可忽略的重要因素。柳氏西眷为寻求家族在中央的发展而入关,虬、桧、庆三人在其中扮演了不同角色,这种努力表现为“共时性”的协作和“历时性”的接力。家族在柳虬去世前因获赐“乙弗”姓氏而成为西魏“官族”,后因柳庆获得赐姓“宇文”而跻身北周核心圈层,河东柳氏西眷在西魏北周进入勃兴期,为家族在隋唐时期的鼎盛奠定了基础。

The mechanism of lightning that ignites a forest fire and the lightning that occurs above a forest fire are explained at the molecular level. It is based on two phenomena, namely, internal charge separation inside the atmospheric cloud particles and the existence of a layer of positively charged hydrogen atoms sticking out of the surface of the liquid layer of water on the surface of rimers. Strong turbulence-driven collisions of the ice particles and water droplets with the rimers give rise to breakups of the ice particles and water droplets into positively and negatively charged fragments leading to charge separation. Hot weather in a forest contributes to the updraft of hot and humid air, which follows the same physical/chemical processes of normal lightning proposed and explained recently[1]. lightning would have a high probability of lighting up and burning the dry biological materials in the ground of the forest, leading to a forest (wild) fire. The burning of trees and other plants would release a lot of heat and moisture together with a lot of smoke particles (aerosols) becoming a strong updraft. The condition for creating lightning is again satisfied which would result in further lightning high above the forest wild fire.
