China\u2019s national departments at all levels have developed relevant ocean engineering equipment industry policies to promote the rapid development of the industry. By using 56 industrial policies issued between 2010 and 2020 as the research sample, we conducted an in-depth assessment of the external structural characteristics and structure of the main cooperation network for such policies using descriptive statistics and social network analysis. Based on a symmetric analysis method, the two-dimensional matrix of cooperation breadth and cooperation depth, together with the measurement of the issuing subject\u2019s centrality, was used to analyze the evolution of the subject\u2019s role in the network. The research shows that the development of China\u2019s ocean engineering equipment industry policies can be divided into three stages, and there are the following problems during the development of policies: (1) some policies and regulations are imperfect; (2) the network of cooperation among joint issuers is limited; and (3) some policies are issued by multiple government departments, but there is a lack of specialized and unified management from an absolute core department. Based on the above problems, we present some suggestions for policy optimization at the end of this paper.<\/jats:p>","DOI":"10.3390\/sym14061115","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"1115","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["TEXT Analysis on Ocean Engineering Equipment Industry Policies in China between 2010 and 2020"],"prefix":"10.3390","volume":"14","author":[{"given":"Jiajia","family":"Ren","sequence":"first","affiliation":[{"name":"School of Economics and Management, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}]},{"given":"Shilun","family":"Ge","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Jiangsu University of Science and Technology, Zhenjiang 212100, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"691","DOI":"10.1007\/s11135-006-9020-z","article-title":"Text Analysis for Knowledge Graphs","volume":"41","author":"Popping","year":"2006","journal-title":"Qual.
