This paper mainly uses quantitative research methods such as bibliometrics and social network analysis to analyze the correlation between degree centrality, L\u2010index, and scientific performance of the Chinese author of Physical Education and Training Science and draws the following conclusions: (1) degree centrality is positively correlated with the number of papers, average citations per paper, and H\u2010index and (2) L\u2010index is positively correlated with the number of papers, average citations per paper, and H\u2010index. Unlike previous studies on scientific collaboration networks and scholars\u2019 performance that focused on traditional network characteristics indicators, this study introduces a new network characteristics indicator, L\u2010index, through which the degree of collaboration between authors and other important authors in the research field can be better assessed, which also provides a new direction for research related to research collaboration networks and scholars\u2019 performance; at the same time, it also provides a theoretical basis for subsequent research on the utility of scientific collaboration, a reference for the assessment of the research performance of scholars in other disciplines, and a theoretical reference for more scientific and comprehensive prediction of scholars\u2019 research performance in the future.<\/jats:p>","DOI":"10.1155\/2021\/3066602","type":"journal-article","created":{"date-parts":[[2021,9,30]],"date-time":"2021-09-30T21:00:28Z","timestamp":1633035628000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Influence of Author Degree Centrality and L\u2010Index on Scientific Performance of Physical Education and Training Papers in China Based on the Perspective of Social Network Analysis"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3666-4653","authenticated-orcid":false,"given":"Bin","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2606-6422","authenticated-orcid":false,"given":"Jian","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9666-6741","authenticated-orcid":false,"given":"Qian","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0875-4635","authenticated-orcid":false,"given":"Yujiao","family":"Tan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0415-4117","authenticated-orcid":false,"given":"Lu","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8400-6298","authenticated-orcid":false,"given":"Qian","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7629-4314","authenticated-orcid":false,"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9918-3729","authenticated-orcid":false,"given":"Miao","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6827-2593","authenticated-orcid":false,"given":"Wei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,9,30]]},"reference":[{"key":"e_1_2_10_1_2","first-page":"443","article-title":"Little science, big science","volume":"7","author":"Price D.
