长三角地区高新技术产业政策文本量化研究OACSTPCD

This paper aims to reveal the evolutionary characteristics of high-tech industry policies in the Yangtze River Delta Region,and provide reference suggestions for policy makers to optimize top-level design and improve policy systems.Taking 919 high-tech industry policy texts in the Yangtze River Delta Region from 1991 to 2022 as the research object,based on the dimensions of policy themes,policy issuers,and policy tools,this paper uses natural language processing,2-mode network analysis,and topic coding methods to conduct a quantitative analysis on high-tech industry policy texts,and presents the results visually.The research shows that:①In terms of policy themes,the fields concerned by the government are more and more diversified,systematic,and specific.More emphasis is placed on macro guidance and the use of administrative means,but market and integrated development of the Yangtze River Delta Region are less involved.②In terms of the policy issuers,municipal and lower level policy issuers begin to play a major role,and policy issuers become more specialized,personalized,and ground-rooted,but the location distribution of policy issuers is not balanced enough.③In terms of policy tools,environmental policy tools are most commonly used,while demand-based policy tools are underutilized,and the use of policy tools is related to regions,development stages,and historical backgrounds.Based on the above issues,specific policy recommendations have been proposed,including enhancing regional synergy of policies,establishing a sound market-oriented mechanism for high-tech industry policies,and optimizing the use of policy tools.
