In this paper, the author analyzes the regional technological innovation and green economic efficiency based on DEA model and fuzzy evaluation. Based on the latest development of traditional efficiency and productivity analysis theory, this study calculates the green innovation efficiency of 30 provincial industrial enterprises by using SBM model, while considering the relaxation of economic input-output problem. The results show that the SBM model improves the accuracy and authenticity of the economic efficiency evaluation of green innovation. The efficiency of green economy in most provinces is on the rise. At the same time, the intensity of R&amp;D and industrial structure play a positive role in improving the efficiency of green economy. Through cluster analysis, the differences and causes of green economic efficiency of regional industrial enterprises are analyzed. In addition, the provinces should also consider the factors affecting the green economic efficiency of industrial enterprises, implement the innovation-driven development strategy in an all-round way, and promote the development of green economy.<\/jats:p>","DOI":"10.3233\/jifs-179220","type":"journal-article","created":{"date-parts":[[2019,6,11]],"date-time":"2019-06-11T11:47:26Z","timestamp":1560253646000},"page":"6415-6425","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":29,"title":["Regional technological innovation and green economic efficiency based on DEA model and fuzzy evaluation"],"prefix":"10.1177","volume":"37","author":[{"given":"Qinyang","family":"Li","sequence":"first","affiliation":[{"name":"School of Economics and Management, Yantai University, Yantai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,6,6]]},"reference":[{"issue":"3","key":"e_1_3_1_2_2","first-page":"2699","article-title":"PREA: Personalized recommendation algorithms toolkit","volume":"13","author":"Lee J.","year":"2014","unstructured":"LeeJ., SunM. and LebanonG., et al., PREA: Personalized recommendation algorithms toolkit, Journal of Machine Learning Research 13(3) (2014), 2699\u20132703.","journal-title":"Journal of Machine Learning Research"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00779-016-0923-y"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2013.168"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCI.2014.2369894"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10639-012-9245-5"},{"issue":"10","key":"e_1_3_1_7_2","first-page":"244","article-title":"Study of shanxi\u2019s green innovation efficiency of industrial enterprises based on SBM model and four-stage DEA approach","author":"Niu T.","year":"2015","unstructured":"NiuT., PengS.Y., NiuC.H., et al., Study of shanxi\u2019s green innovation efficiency of industrial enterprises based on SBM model and four-stage DEA approach, Science and Technology Management Research (10) (2015), 244\u2013249.","journal-title":"Science and Technology Management Research"},{"issue":"4","key":"e_1_3_1_8_2","first-page":"71","article-title":"Research on spatial spillover effect of regional science and technology resource allocation efficiency under the environmental constraints","author":"Qian L.","year":"2016","unstructured":"QianL., XiaoR.Q., ChenZ.W., et al., Research on spatial spillover effect of regional science and technology resource allocation efficiency under the environmental constraints, Chinese Soft Science(4) (2016), 71\u201380.","journal-title":"Chinese Soft Science"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-2217(01)00324-1"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1145\/2663356"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2015.01.045"},{"issue":"7","key":"e_1_3_1_12_2","first-page":"1470","article-title":"Survey of Online Social Network Based Personalized Recommendation","volume":"35","author":"Fu-Guo Z.","year":"2014","unstructured":"Fu-GuoZ., Survey of Online Social Network Based Personalized Recommendation, Journal of Chinese Computer Systems 35(7) (2014), 1470\u20131476.","journal-title":"Journal of Chinese Computer Systems"},{"key":"e_1_3_1_13_2","doi-asserted-by":"publisher","DOI":"10.1109\/THMS.2015.2509965"},{"key":"e_1_3_1_14_2","doi-asserted-by":"publisher","DOI":"10.15388\/infedu.2016.03"},{"key":"e_1_3_1_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/asi.20631"},{"key":"e_1_3_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physa.2016.03.070"},{"key":"e_1_3_1_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipl.2014.09.022"},{"key":"e_1_3_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2016.01.023"},{"key":"e_1_3_1_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijar.2013.04.002"},{"key":"e_1_3_1_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2016.03.006"},{"key":"e_1_3_1_21_2","doi-asserted-by":"publisher","DOI":"10.1145\/2934681"},{"key":"e_1_3_1_22_2","doi-asserted-by":"publisher","DOI":"10.1177\/0165551515603321"},{"key":"e_1_3_1_23_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11761-013-0140-8"},{"key":"e_1_3_1_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2015.07.026"},{"key":"e_1_3_1_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2016.08.022"},{"key":"e_1_3_1_26_2","doi-asserted-by":"publisher","DOI":"10.1108\/JEDT-02-2013-0017"}],"container-title":["Journal of Intelligent &amp;
