【摘要】 新基建成为当前应对疫情冲击、贸易壁垒、经济下行，助力创新驱动发展战略的一项重要举措。文章运用内容分析法，从政策工具和创新价值链两个维度对我国31个省份(港澳台除外)的新基建政策文本进行内容编码、统计描述和量化分析，比较分析新基建的政策工具和创新价值链各环节的应用差异以及二者的交叉效应。研究发现，政策工具的分布差异性较为明显，主要集中于供给型和环境型两类政策工具，在具体的组合上存在结构性失衡现象；新基建政策主要集中于创新价值链的研究开发环节，产业化和市场化环节的具体政策应用不足；各类政策工具在新基建创新价值链不同环节的应用存在明显差异。针对地方政府新基建政策存在的问题提出相应的优化建议。更多还原

【Abstract】 New infrastructure is an important initiative to cope with the current epidemic impact, trade barriers and economic downturn, and to support the innovation-driven development strategy.This article uses the content analysis method to carry out content coding, statistical description and quantitative analysis of the new infrastructure policy texts of 31 provinces in china(excluding Hong Kong, Macao and Taiwan)from the perspectives of policy tools and innovation value chain, to compare and analyze the application differences of policy tools for new infrastructure and the application of different links in the innovation value chain, as well as the cross-effects of the two.The research found that the distribution of new infrastructure policy tools is more obvious, mainly focusing on supply-oriented and environment-oriented policy tools, and there is a structural imbalance in the specific combination.Policies mainly focus on the research and development links of innovation value chain, and the relevant policies in the industrialization and marketization links are insufficiently applied.There are obvious differences in the application of different types of policy tools in each link of the innovation value chain.In view of the problems existing in the local government’s new infrastructure policy, corresponding optimization suggestions are put forward.更多还原
