Abstract The objective of this research is to analyze the relationship between size and growth through the validation of Gibrat's law. A sample of 17,082 Ecuadorian companies in the service sector is used for the period 2010–2015. The estimation method used is that of quantile regression for panel data; the results suggest that small companies grow faster than their larger counterparts. The results show that the growth, measured through sales and employment, of SMEs in the service sector in Ecuador is not independent of firm size and therefore does not correspond to a random process.

吉布拉特定律的有效性：来自厄瓜多尔服务业中小企业的证据

摘要这项研究的目的是通过验证吉布拉特定律来分析规模与增长之间的关系。在2010-2015年期间，使用了17,082家厄瓜多尔服务业公司的样本。使用的估计方法是面板数据的分位数回归；结果表明，小公司的增长速度快于大公司。结果表明，厄瓜多尔服务业中小型企业的增长（通过销售和就业来衡量）并非独立于企业规模，因此不符合随机过程。
