The results show that with the increase of the natural growth rate of energy, the stability of the system is not affected, but the market demand of the oligopoly 1 is gradually reducing and the market demand of the oligopoly 2 is gradually increasing. At the same time, a single oligopoly making the time delay decision will affect the stability of the two oligopolies. With the increase of delay, the time required to reach the stable state will grow, and the system will eventually enter the Hopf bifurcation, thus the system will have its entropy increased and fall into an unstable state. Therefore, in the actual market of renewable energy, oligopolies should pay attention to the natural growth rate of energy and time delay, ensuring the stability of the game process and the orderliness of the system.<\/jats:p>","DOI":"10.3390\/e19010022","type":"journal-article","created":{"date-parts":[[2017,1,9]],"date-time":"2017-01-09T11:03:23Z","timestamp":1483959803000},"page":"22","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Research Entropy Complexity about the Nonlinear Dynamic Delay Game Model"],"prefix":"10.3390","volume":"19","author":[{"given":"Xueli","family":"Zhan","sequence":"first","affiliation":[{"name":"College of Management Economic, Tianjin University, Tianjin 300072, China"},{"name":"School of Economics, Beijing Wuzi University, Beijing 101149, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junhai","family":"Ma","sequence":"additional","affiliation":[{"name":"College of Management Economic, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenbo","family":"Ren","sequence":"additional","affiliation":[{"name":"College of Management Economic, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1225","DOI":"10.1016\/S0301-4215(03)00086-7","article-title":"Energy for Sustainable Development in China","volume":"32","author":"Weidou","year":"2004","journal-title":"Energy Policy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"921","DOI":"10.1016\/j.eneco.2004.04.003","article-title":"Emission Policies and the Nigerian Economy: Simulations from a Dynamic Applied General Equilibrium Model","volume":"26","author":"Nwaobi","year":"2004","journal-title":"Energy Econ."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"875","DOI":"10.1016\/j.energy.2006.08.006","article-title":"Energy Indicators for Sustainable Development","volume":"32","author":"Vera","year":"2007","journal-title":"Energy"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"951","DOI":"10.1016\/j.rser.2014.07.084","article-title":"An international literature survey on energy-economic growth nexus: Evidence from country-specific studies","volume":"38","author":"Omri","year":"2014","journal-title":"Renew.
