摘　　要：拓展迪克西特—斯蒂格利茨的垄断竞争模型,基于粤港澳大湾区9市2008—2018年的面板数据,验证高新技术企业集聚和经济增长的促进关系,实证表明在考虑三次项的影响后,集聚对经济增长存在两个拐点效应,呈先减后增再减的趋势;同时,大部分城市在研究时间段内集聚程度并未超过第二个拐点,说明高新技术企业集聚对经济增长的促进作用显著且具有较大的潜力空间。因此,欠发达地区可借鉴粤港澳大湾区的经济发展经验,努力打造高新技术产业集聚“核心区”,发挥协同效应促进优势互补,引领区域高质量发展。This paper,by expanding the Dixit-Stiklitz monopolistic competition model,based on the panel data(2008—2018)of 9 cities in the Guangdong-Hong Kong-Macao Greater Bay Area,aims to verify the relationship between high-tech enterprises agglomeration and economic growth.Empirical evidence shows that 1)considering the effects of the cubic item,agglomeration has two inflection point effects on economic growth,showing a trend that decreasing comes first,followed by increasing and then it shifts to decreasing;2)the degree of agglomeration in most cities during the research period does not exceed the second inflection point,indicating that the agglomeration of high-tech enterprises has a significant role and a large potential space in promoting economic growth.Therefore,underdeveloped regions can learn from the economic development experience of the Guangdong-Hong Kong-Macao Greater Bay Area,that is,to strive to form a“core area”for high-tech industry clusters,give play to synergy for utilizing complementary strengthens so as to lead regional high-quality development.
