在传统的国家层面出口复杂度指标的基础上，提出了三个衡量新能源产业出口复杂度的指标。同时，利用联合国商品贸易统计数据库中30个国家2000 - 2015年的数据，计算和比较了全球细分新能源产品和新能源产业在跨国层面的出口复杂度。并通过区域异常检验，分析了典型县域新能源产业发展水平。研究结果表明，新能源产品的技术含量从高到低依次为风能、生物质能、核能、太阳能，而考虑产品质量差异时，核电产品的技术含量高于生物质能产品。此外，各国新能源产业的技术含量在一定程度上呈现出区域异质性：欧洲新能源产业的技术含量随着时间的推移呈现出越来越明显的优势;亚洲新能源产业的技术含量与其他国家的差距越来越大;而美国新能源产业的技术含量则逐渐追赶其他国家。
Based on the traditional export sophistication indices used at a national level, three indices for measuring the export sophistication of the new energy industry are proposed. Meanwhile, data from 30 countries from 2000 to 2015 in the UN Comtrade database are used to calculate and compare export sophistication of global sub-divided new energy products and new energy industries at a transnational level. Moreover, the development levels of new energy industries in typical counties and regions are analysed through use of a regional anomaly test. The research results demonstrate that new energy products are ranked, in descending order, as: wind, biomass, nuclear, and solar energy products according to their technical contents, while nuclear power products show higher technical content than biomass energy products when considering product quality differences. Besides, the technical contents of new energy industries in different countries show regional heterogeneity to a certain extent: the new energy industries in Europe present increasingly evident superiority with time in terms of the technical content; the technical content of new energy industries in Asia presents a growing gap with other countries; while the technical content of new energy industries in America gradually catches up with other countries.
