本文通过重新构建新经济指数的指标体系，收集数据测算和评价了22个国家新经济的发展程度，研究发现新经济指数最高的是美国，其次是日本和中国；创新能力、数字化、网络化、智能化得分最高的都是美国，而全球化和绿色化得分最高的分别是荷兰和瑞士。经济基础和科技能力是新经济发展的前提条件，而结构失衡是制约新经济发展的核心因素。
Through reconstructing the index system of the new economic index，we collecte the data to estimate and evaluate the development degree of the new economy in 22 countries. The study finds that the highest new economic index is the United States，followed by Japan and China；the highest scores on innovation ability，digitalization，networking and intelligentization are all in the United States，while the highest scores on globalization and greenization are separately in Netherlands and Switzerland. Economic level and technological capability are prerequisites for the development of new economy，while structural imbalance is the core factor that restricts the development of new economy.
