Research Methods:Based on text data from the Chinese government work reports and corporate annual reports from 2009 to 2018, this paper employs data text analysis technology to measure the policy correlation between the corporate annual report and the government work report text, and estimates the impact of policy correlation on corporate performance. Research Findings:First, the corporate‘s policy correlation has increased significantly after 2012. Second, companies with higher policy correlation are characterized with private, small or medium-sized, eastern located, light-asset, low financial leverage, good funding, and riskier. Third, higher policy correlation leads to the better performance of these enterprises, especially for the private, small or medium-sized and eastern enterprises. Fourth, high policy correlation enterprises are less financing constraints and more government-subsidized and tax incentives. Fifth, after deducting government subsidies and tax incentives, there is still a positive relationship between policy correlation and corporate performance, which means that strategic innovation for obtaining policy-related benefits is not the only way for policies to be effective. Research Innovations:This paper creatively combines text data analysis technology, and uses a similarity algorithm to measure the degree of policy correlation between annual reports and government work reports and provides a new perspective for quantitative policies. Research Value: The method in this paper provides a reference value for the use of text data analysis technology to study economic issues, and the research conclusions provide suggestions for the government to optimize policy implementation methods and improve policy implementation efficiency. | | 查看全文 |
