Meantime, environmental pollution caused by energy consumption is a problem that immediately needs to be solved. To adapt to China\u2019s rapidly emerging economy, and based on existing policies, giving more consideration to energy saving and environmental safety is more important. Therefore, to investigate China\u2019s regional environmental efficiency and its factors has key importance. In order to evaluate the environmental efficiency input in China, this study first selects some indexes of environmental efficiency and applies the Data Envelopment Analysis (DAE) method to measure the efficiency of input and output. Then, the relative index of environmental efficiency input is selected as the input variable and the efficiency value as the output variable. The Backpropagation neural network is employed to learn and establish the prediction model and achieve high prediction accuracy. The performance of the model is improved by optimizing the index of environmental efficiency investment, adopting the latest data, and increasing the learning samples. This method is not only suitable for the evaluation of macro-environmental efficiency investment, but also suitable for enterprises in specific industries.<\/jats:p>","DOI":"10.1155\/2021\/3766980","type":"journal-article","created":{"date-parts":[[2021,11,15]],"date-time":"2021-11-15T19:20:06Z","timestamp":1637004006000},"page":"1-7","source":"Crossref","is-referenced-by-count":3,"title":["Environmental Efficiency Evaluation Method Based on Data Envelopment Analysis and Improved Neural Network"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0374-4991","authenticated-orcid":true,"given":"Chao","family":"Yang","sequence":"first","affiliation":[{"name":"School of Economics and Management, University of Science and Technology Beijing, Beijing100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"He","sequence":"additional","affiliation":[{"name":"School of Economics and Management, University of Science and Technology Beijing, Beijing100083, China"},{"name":"College of Economics Management and Law, Hubei Normal University, Huangshi 435002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang","family":"Ren","sequence":"additional","affiliation":[{"name":"CNPCPetrochina Planning and Engineering Institute, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","first-page":"740","article-title":"Environmental efficiency on efficiency and effect evaluation of environmental efficiency investment in China","volume":"6","author":"H.
