主营业务增长率是指企业本年主营业务收入增长额与去年主营业务收入总额的比率，它反映了企业主营业务的增长速度和盈利能力。

具体来说，主营业务增长率可以通过以下公式计算：主营业务增长率 = （本年主营业务收入 - 去年主营业务收入）/ 去年主营业务收入 × 100%。

主营业务增长率可以用来评估企业成长性和盈利能力的强弱。如果主营业务增长率较高，说明企业产品或服务的需求市场在扩大，企业的竞争力在提高，从而能够带来更多的利润。反之，如果主营业务增长率较低或出现负增长，则可能说明企业产品或服务的需求市场在萎缩，或者企业在市场竞争中处于劣势地位，这可能会对企业的盈利能力和未来发展产生负面影响。

此外，主营业务增长率也可以用来预测企业的发展趋势。通过观察主营业务增长率的连续变化，可以了解企业是否在持续发展或调整其业务结构。如果主营业务增长率呈现持续上升的趋势，说明企业在不断扩大其市场份额或提高其产品或服务的竞争力；反之，如果主营业务增长率呈现持续下降的趋势，则可能说明企业在市场竞争中逐渐失去优势。

总之，主营业务增长率是评估企业成长性和盈利能力的重要指标之一。通过对主营业务增长率的计算和分析，可以帮助我们了解企业的经营状况和发展趋势。
