俄罗斯-乌克兰战争的经济成本：（失去的）企业家精神的综合控制研究
The Economic Costs of the Russia-Ukraine War: A Synthetic Control Study of (Lost) Entrepreneurship
摘要：
这项综合控制研究量化了自2014年入侵克里米亚以来俄乌战争在两国放弃的创业活动方面的经济成本。相对于其合成的反事实，乌克兰的自营职业者人数减少了675，000人，相当于相对损失20%。乌克兰中小企业的数量暂时下降了71，000（14%），并在冲突后五年内恢复。相比之下，俄罗斯在冲突五年内损失了140多万中小企业（42%）。俄罗斯中小企业的消失是由于新企业的减少和现有企业的关闭。
英文摘要：
This synthetic control study quantifies the economic costs of the Russo-Ukrainian war in terms of foregone entrepreneurial activity in both countries since the invasion of Crimea in 2014. Relative to its synthetic counterfactual, Ukraine's number of self-employed dropped by 675,000, corresponding to a relative loss of 20%. The number of Ukrainian SMEs temporarily dropped by 71,000 (14%) and recovered within five years of the conflict. In contrast, Russia had lost more than 1.4 million SMEs (42%) five years into the conflict. The disappearance of Russian SMEs is driven by both fewer new businesses created and more existing business closures.
