2010年4月,雷军创办小米,2011年8月16日小米I代惊艳亮相,一年之后,历经重重困难的小米才勉强站稳脚跟。2013年,小米开始步入发展快车道。此时,雷军提出了“飞猪理论”,即站在台风口,猪也能飞起来。“飞猪理论”的本质并不复杂,概括起来就四个字:顺势而为。

    伴随着“飞猪理论”的迅速走红,争议也由此而来,不少大佬矛头直指“飞猪理论”。如马云认为,“猪碰上风也会飞,但是风过去摔死的还是猪,因为你还是猪。”百度李彦宏在出席IT领袖峰会时也对“飞猪理论”表示不满,他认为其充满投机思维。

面对外界的质疑,雷军不得不对“飞猪理论”做出更全面的解释,反复提及“1万小时定律”和“选择比努力重要”两大理论,前者是“飞猪理论”的前提,没有深厚积累即便遇到发展良机,也会失之交臂;后者是“飞猪理论”的核心,“不能只顾埋头苦干,不去抬头看路。应该花足够时间研究风向,研究风口,这样你成功的概率要大很多。”

    中国经济正处于新旧动能的转换期,传统的经济业态正转型升级,“互联网+”等这些站在“风口”的新的经济业态也层出不穷。新业态的健康发展离不开政府的必要放权、引导支持和监督管理。正如***所说,要深化简政放权、放管结合、优化服务改革,把“放、管、服”有机结合起来。
