Abstract

Whether the industrial policy can promote the high-quality development of manufacturing industry, a large number of scholars have conducted empirical research on the effectiveness of tax policy, R&D policy and other aspects, but few scholars have studied how the effectiveness is affected. Our research will try to fill the gap in this problem. Since manufacturing policies involve multiple fields, and different policies have different impacts, we need to analyze these policies as a whole and consider the impact of the relationship network between policy texts on the overall development of manufacturing. This can explain the impact of policies. We collected 95 manufacturing policy texts from 2011 to 2020 in Zhejiang Province and established a relationship network using the sector information and keyword information contained in the text data. We apply the complex network analysis method to the analysis of the relationship characteristics of policy texts and calculate the centrality, structural holes and other indicators of the relationship network. We further found that the characteristics of policy text relations have a significant impact on the production of policy effects by using the GRA (Grey Relation Analysis) and coupling coordination methods. The number of departments involved in the formulation of policy texts and the tightness of keywords have a positive impact on the policy effect. This enlightens the government to make unified policies based on departmental cooperation and strengthen the connection between policy texts and policy objectives. This research shows that text data can identify the value transmission law of policy effects, reveals the causes that affect the policy effects and provides the government with more practical operational plans in policy formulation.
