Compared with previous studies, the proposed measure can fully rank the overall environmental efficiency of all decision making units (DMUs) in a dynamic manner, and more importantly, it provides the information about when and what factors lead to inefficiency or efficiency of DMUs. The proposed models are applied to examine the environmental efficiency of 30 provinces in China from 2008 to 2017. The results show that there are significant regional differences of environmental efficiency in China. In addition, slack analysis shows that most eastern efficient provinces have no obvious advantages in energy consumption, labor and waste water emission; most central and western efficient provinces have no advantages in sulfur dioxide (SO2) emissions and GDP. To improve overall efficiency, eastern inefficient provinces should mainly focus on reducing energy consumption, SO2 emissions and labor, and increasing capital investment in right years, central and western inefficient provinces can focus on reducing SO2 emissions and labor in most years, most of provinces need to increase gross domestic capital formation.<\/jats:p>","DOI":"10.1371\/journal.pone.0290896","type":"journal-article","created":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T17:30:52Z","timestamp":1693503052000},"page":"e0290896","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":5,"title":["Intertemporal environmental efficiency assessment in China: A new network-based dynamic super-efficiency measure"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8068-7716","authenticated-orcid":true,"given":"Ruiyue","family":"Lin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zongxin","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,8,31]]},"reference":[{"issue":"6","key":"pone.0290896.ref001","doi-asserted-by":"crossref","first-page":"429","DOI":"10.1016\/0377-2217(78)90138-8","article-title":"Measuring the efficiency of decision making units","volume":"2","author":"A Charnes","year":"1978","journal-title":"European Journal of Operational Research"},{"key":"pone.0290896.ref002","doi-asserted-by":"crossref","first-page":"1552","DOI":"10.1016\/j.apenergy.2015.02.066","article-title":"Is there a difference between the energy and CO2 emission performance for China\u2019s thermal power industry?
