让弹性保障发挥作用
1704516913
1704516914
丹麦的弹性保障模式具有双重优势,既减少了可能制约创造性破坏进程的劳动力市场的僵化,[20]又给人们的职业道路提供某些保障,使他们能更为平缓地度过失业期,减少收入损失,并有望快速回到就业状态。对劳动者而言,弹性保障意味着从“岗位保障”转向“就业保障”或者说“就业能力保障”(employability),便于适应创新带来的更频繁的职业转换。欧盟理事会认为,弹性保障“需要灵活可靠的合同安排……全面的终身学习策略,有效的积极劳动力市场政策,以及现代社会保障体系”。[21]

正如该机构所述,职业培训与技能培训是成功的职业转换的关键因素。为强调这点,两位丹麦学者奥维·彼得森(Ove Kaj Pedersen)与索伦·安德森(Sϕren Kaj Andersen)发明了“流动性教育”(mobication)的概念,把流动性(mobility)与教育(education)结合起来。[22]此概念背后的思想是,技能发展不仅能促进劳动力市场内部的流动性,还可以提高应对挑战的能力,例如我们在第3章讨论的人工智能革命等新挑战。

创造性破坏的力量 4.结论

1704516924
创造性破坏会如何影响人们的真实生活经历?在本章中,我们指出创造性破坏将提高失业乃至更普遍的失去地位的概率。此外,它对美国人的健康造成了消极影响,但在丹麦并非如此。最后,创造性破坏对个人生活满意度有双向作用:一方面增加焦虑感,另一方面提升对未来就业和增长的期望。总体而言,创造性破坏未必会导致健康恶化、幸福感下降,一切还取决于制度环境。为争取支持并避免滑向民粹主义,必须有社会安全网来辅助创造性破坏过程。如近期的新冠疫情所示,第一个安全网是全民普及的高质量医疗服务。第二个安全网是最低收入体系,以消除贫困陷阱。第三个安全网则是弹性保障体系,给予创新企业招募和解聘员工所需的灵活性,同时给人们的职业发展提供保障。这样的保障以充分的失业保险和有效的终身培训相结合为基础,让人们能更容易找到新的工作。这里也是政府应该发挥作用的地方,作为保险人应对创造性破坏和失业带来的风险,以及作为投资人促进教育和创新。我们将在第14章以及全书结语部分更详细地探讨最后一点,并总结资本主义的未来。
