发展蓝色经济应当继续加强节能降耗

近年来，山东在区域特色经济培育中取得了一定的进展，初步形成了以蓝色经济为主导的区域经济特色。但由于能源消费速度超过经济增长速度，节能降耗势在必行。本文运用“压力一状态一响应”模型构建了山东能源可持续利用的评价指标体系，对山东节能降耗情况进行了现状分析，并运用数据包络分析技术进行基于DEA的山东城市能源利用效率评价，以及基于DEA的Malmquist指数方法估计山东能源全要素生产率。在此基础上，提出了促进山东节能降耗的政策建议。

Strengthening Energy-saving to Develop Blue Economy

In recent years, Shandong province has made some progresses in cultivating regional characteristical economy, initially forming a blue-economy oriented regional economy characteristics. However, the rate of energy consumption rate is faster than that of economic growth, it is imperative to save energy and reduce consumption. In this paper, by using "pressure –status- respond " model we build an evaluation index system for sustainable energy of Shandong province, to make a status analysis on saving energy and reducing consumption of Shandong, and evaluate urban energy efficiency based on Data Envelopment Analysis technology, as well as estimate total factor productivity of Shandong energy by taking the DEA-based Malmquist index method. Finally, we advance recommendations for promoting saving energy and reducing consumption in Shandong.
