Investment Rating - The report does not explicitly provide an investment rating for the industry Core Insights - The value of a statistical life (VSL) is crucial for cost-benefit analysis (CBA) in road safety and socio-economic cost calculations of road crashes, particularly in low- and middle-income countries (LMIC) where specific VSL estimates are often lacking [2][9] - A new value transfer approach is proposed to estimate VSL in countries without specific data, utilizing income elasticities to adapt VSL estimates from other countries [5][12] - The study emphasizes the need for more VSL research in LMICs, highlighting the limited number of existing studies [5][31] Summary by Sections Methodology - A unit value transfer approach is utilized, determining a base VSL from 32 countries to estimate VSL in other nations based on income per capita [3][4] - The resulting VSL transfer functions are defined for LMIC and high-income countries (HIC), with specific equations relating VSL to Gross National Income (GNI) per capita [4][31] Results - The VSL for LMIC ranges from approximately 22,000 USD to 1.1 million USD, while for HIC it ranges from 1.2 million USD to 4.8 million USD [4][25] - The mean VSL is reported as 2.6 million USD, with significant variation observed between LMIC and HIC [23][28] Recommendations - The report recommends applying the new VSL transfer approach for CBA in countries lacking appropriate country-specific VSL, and suggests developing transfer functions for non-fatal injuries [5][33] - Future research should focus on increasing the number of VSL studies in LMIC, particularly in low-income countries [31][35]

鸿蒙电脑 观察者网 对于华为的未来,任正非也保持着危机意识。他表示:"到今天,也还不能说我们就能活下来。中国99%的公司是可以与美国合作的,它们没有受到制裁, 它们的芯片算力比我们的高,它们能买到的东西比我们的好。在这样的条件下,未来几年我们能不能为生存活下去?不要看我们今天和大家欢聚一堂,以为 我们有伟大的梦想,不是,我们还在挣扎中。" 为了挖掘鸿蒙背后的诸多故事,我的访谈记录本已经有一寸(约3.3厘米)之厚,访谈名单也大大超出了原计划的50人左右,逐渐突破100人。这些访谈对象涵 盖了开发者、合作伙伴、用户、专家以及行业内的众多参与者。而记录本最前面的是徐直军的三幅手画图,一页一图,清晰地诠释了鸿蒙的战略方向。"三 分天下有其一"是第一幅图的标题。这几幅图是2021年10月16日晚上,他在深圳万象城的星巴克画下来的。那时候,虽然单框架鸿蒙还没有正式立项,但是 徐直军的心中已经有了清晰的战略规划和目标。中国市场仅仅是鸿蒙的起点;面向全球,与谷歌安卓和苹果iOS一决高下,才是鸿蒙的目标。华为一直在谋 划NEXT的next。 虽然,"生态"一词在中国早已经用滥,但是真正的产业级生态在中国还是空白。没有操作系统和 ...
