数字经济、人才流动与长三角地区高质量发展

数字经济技术在产业转型和经济高质量发展中扮演着越来越重要的角色。基于2011—2018年长三角“三省一市”共41个城市数据,测度了长三角地区数字经济和高质量发展的综合水平,分析数字经济对长三角地区高质量发展的影响,创新性地构造了人才流动不平衡指标,并探讨区域内人才流动不平衡对二者关系的调节效应。研究发现：长三角地区高质量发展水平和数字经济规模逐年上升。数字经济发展通过提升生产效率、流通效率和社会便利促进长三角地区高质量发展,非核心区域的正影响强度大于核心区域。人才流动不平衡会逆向调节数字经济对长三角地区高质量发展的正影响程度,但这一调节效应存在区域异质性。此外数字经济对长三角地区高质量发展存在经济距离为权重矩阵的空间负向溢出效应。

Imbalance of talent flow,digital economy and high-quality development of Yangtze River Delta Economic Zone

Digital economy technology plays an increasingly important role in industrial transformation and high-quality economic development. Based on 41 cities of the Yangtze River Delta from 2011 to 2018, this paper analyzes the impact of digital economy on the high-quality development of the integration of the delta region, and creatively constructs an imbalance index of talent flow to explore the adjustment effect of the imbalance of talent flow in the region on the relationship between digital economy and high-quality development. The results show that the high-quality development level and the scale of digital economy in the Yangtze River Delta integration are increasing year by year. The development of digital economy has a positive impact on the high-quality development by improving the production efficiency, circulation efficiency and social convenience. The positive impact of non-core areas is stronger than that of core areas. The imbalance of talent flow will reversely regulate the positive impact of digital economy on the high-quality development, but this impact is only found in the core area of the Yangtze River Delta. In addition, digital economy has a negative spatial spillover effect with economic distance as the weight matrix.
