请翻译成英文 在常规性分析中，我们首先会聚焦在用户增长的策略效率上，按照不同场景（如内容场景及货架场景），不同目的（如拉新、复购、召回）的策略，分别从用户价值、策略效率以及规模三个角度进行分析，从而提出针对不同策略扩大投入或减少投入的建议

In regular analysis, we first focus on the efficiency of user growth strategies, analyzing from three perspectives: user value, strategy efficiency, and scale, according to different scenarios (such as content and shelf scenarios) and different objectives (such as acquiring new users, retaining existing users, and re-engaging inactive users). Based on this analysis, we provide recommendations for increasing or decreasing investment for different strategies.
