contribution到底是算贡献值还是贡献率？

NO.PZ202105270100000201 问题如下 Calculate the impliecontribution to Cambo’s US equity return forecast from the expectechange in the P/E. The growth rate in the aggregate market value of equity is expressea sum of the following four factors: (1) growth rate of nominG, (2) the change in the share of profits in G, (3) the change in P/E, an(4) the vinyiel The growth rate of nominG is the sum of the growth of reG aninflation. The growth rate of reG is estimatethe sum of the growth rate in the labor input anthe growth rate in labor proctivity. Baseon the chief economist’s estimates, the macroeconomic forecast incates thnominG will increase 4.0% (= 0.5% labor input + 1.3% proctivity + 2.2% inflation). Assuming a 2.8% vinyielanno change in the share of profits in the economy, Cambo’s forecast of a 9.0% annuincrease in equity returns implies a 2.2% long-term contribution (i.e., 9.0% equity return − 4.0% nominG − 2.8% vinyiel from expansion in the P/E.权益总市值的增长率表示为以下四个因素的总和:(1)名义G增长率，(2)利润占G份额的变化，(3)市盈率的变化，(4)股息收益率。名义G增长率是实际G增长率和通货膨胀率之和。实际G增长率估计为劳动投入增长率与劳动生产率增长率之和。根据首席经济学家的预测，宏观经济预测显示，名义G将增长4.0%(= 0.5%的劳动投入+ 1.3%的生产率+ 2.2%的通货膨胀)。假设股息收益率为2.8%，且利润在经济中所占的份额不变，Cambo预测股权回报年增长率为9.0%，这意味着市盈率的为2.2%(即9.0%股权回报- 4.0%名义G - 2.8%股息收益率) 如题。
