比较优势comparative advantage


「释义」
比较优势或相对优势是经济学的概念,解释了为何在拥有较低的机会成本的优势下生产,贸易对双方都有利。可分为静态比较优势和动态比较优势。当一方(一个人,一间公司,或一国)进行一项生产时所付出的机会成本比另一方低,这一方面拥有了进行这项生产的比较优势。
比较优势理论源于亚当·斯密的绝对优势理论。李嘉图发展了亚当·斯密的绝对优势理论,在《政治经济学及赋税原理》(1817)中,提出了著名的比较优势理论(Law of Comparative Advantage),李嘉图所确定的比较优势理论的核心是:一个国家倘若专门生产自己相对优势较大的产品,并通过国际贸易换取自己不具有相对优势的产品就能获得利益。李嘉图的理论实际上说明在单一要素经济中,生产率的差异造成比较优势,而比较优势决定了生产模式。
「应用场景」
在员工之间分配任务为管理者创造价值提供了更多机会。英国政治经济学家李嘉图1871年提出的比较优势是一个实用概念。许多人认为这是一种经济理念,我则把它当成道德行为指南。评估比较优势包括让每个人或每家企业衡量如何把时间用在创造最大价值的地方。当企业能够以比竞争对手更低的成本生产和销售产品与服务时,它们就具备了比较优势。当个人能够比他人以更低的机会成本来执行任务时,他们就具备了比较优势。每一个人都有比较优势的来源,相应地分配时间可以创造最大的价值。
Allocating tasks among employees offers managers other opportunities to create value. One helpful concept is the notion of comparative advantage, introduced by the British political economist David Ricardo in 1817. Many view it as an economic idea; I think of it as a guide to ethical behavior. Assessing comparative advantage involves determining how to allow each person or organization to use time where it can create the most value. Organizations have a comparative advantage when they can produce and sell goods and services at a lower cost than competitors do. Individuals have a comparative advantage when they can perform a task at a lower opportunity cost than others can. Everyone has a source of comparative advantage; allocating time accordingly creates the most value.
李嘉图的概念在许多企业中都可以看到。在这些企业中,一个个体在很多事情上极其出色。想象一下,一家科技初创企业的创始人拥有最优秀的技术能力,不过只比第二有才华的技术人员略胜一筹。然而,这位创始人在向投资者宣传公司方面远比其他所有员工更有成效。她在技术问题上具有绝对优势,但她的比较优势在于其与外部支持者打交道,当她将注意力集中在这方面时,就会创造更多的价值。许多管理者本能地利用自己和员工的绝对优势,而不是倚重他们的比较优势。结果可能是资源配置不佳,价值创造较少。
Ricardo’s concept can be seen in many organizations where one individual is truly amazing at lots of things. Picture a tech start-up where the founder has the greatest technical ability but it’s only a bit greater than that of the next-most-talented technical person. Yet the founder is dramatically more effective than all other employees at pitching the company to investors. She has an absolute advantage on technical issues, but her comparative advantage is in dealing with external constituencies, and more value will be created when she focuses her attention there. Many managers instinctively leverage their and their employees’ absolute advantage rather than favoring their comparative advantage. The result can be a suboptimal allocation of resources and less value creation.
