统计研究

我国经济转向高质量发展阶段后，发展新经济培育新动能势在必行。本文从数字能力、经济活力、知识实力、创新动力和潜能助力5个维度构建新经济新动能综合指标体系，借助PP-IPM模型进行权重设置，测算2014—2019年我国31个省（区、市）的新经济新动能指数，利用修正的引力模型考察省域新经济新动能的空间关联强度，采用社会网络分析呈现新经济新动能关联网络的整体形态、内部结构与演进态势。结果显示，我国省域新经济新动能呈东高西低的空间分布特征和先收敛后发散的动态趋势，形成以“高—高”和“低—低”聚集为主的空间格局；地区之间的新经济新动能联系东密西疏，省域新经济新动能的对外辐射和吸纳能力逐步提升，北京、四川等省份大概率占据结构洞位置，表现出明显的发展优势。结论对于推动我国新经济新动能的持续健康协调发展具有启示意义。

China's economy has entered a stage of high-quality development, with the new economy and new impetus being a significant part and a strong driving force. This article builds a new economy and new impetus index(NENII) from the dimensions of digital ability, economic vitality, knowledge strength,innovation power, and potential assistance, and uses the PP-IPM model to set weights and calculates the NENII in 31 provinces of China from 2014 to 2019. The modified gravity model is used to measure the provincial spatial correlation strength, and social network analysis is further used to show the overall form,internal structure and evolution trend of the association network. Results show that the development of the new economy and new impetus of 31 provinces in China exhibits a “high-east, low-west” pattern and the convergence-to-divergence dynamic trend; the whole country has formed a distribution pattern dominated by “low-low” and “high-high” aggregation forms. The inter-regional connections are close in the east and sparse in the west; radiation and absorption capacity has gradually increased. Provinces such as Beijing and Sichuan have a high probability of occupying structural holes and have development advantages. The conclusion has enlightenment for the sustainable, healthy and coordinated development of China's new economy and new impetus.
