策略群组与企业盈利水平的差异

企业之间的盈利水平存在着一定的差异，。这是各个产业中常见的现象。不同领域的学者对此解释不同，比较有影响的解释有产业组织理论的SCP范式，企业战略管理的RBV理论。事实上，盈利水平差异并不仅仅是产业层面或企业层面的因素所决定的，还有一种更为重要的层面－策略群组起着非常重要的作用。因此，企业为了提高自身的盈利能力，必须不断地调整自己在整个策略群组中的地位，或者在不同策略群组之间进行流动。

Strategic Group and the Discrepancy of Firm's Profitability

It is a usual phenomenon in each industry that there is certain discrepancy between every two firms. Scholars in different field have been divergent on the exposition of this phenomenon, among which SCP paradigm in industrial organization theory and RBV theory in business strategic management are more influential. In fact, profit-making discrepancy is not only determined by the factors on industrial layer or firms, and there is a more important layer: strategic group, which play a very significant role on it. Therefore, an enterprise must adjust its position in the strategic group or flow between different strategic groups in order to enhance its profit-making ability.
