提高能源效率是保护环境和节约资源的一项高效政策。以前的研究测量了工业部门的能源效率。我们进一步帮助了解影响能源效率变化的因素。本研究以日本能源密集型产业中的造纸、纸浆、水泥产业为代表，以工厂层面的数据为基础，对能源效率进行了测算。分析了产业集聚效应与各行业能源效率之间的关系。我们的研究结果反映了几个重要的发现。首先，2000年至2010年期间，造纸和纸浆工业以及水泥工业的能源效率有所提高。然而，提高能源效率的因素因行业而异。其次，产业集聚影响能源效率。在造纸和纸浆工业，同一产业集群有助于提高能源效率。然而，集聚效应对水泥行业的能源效率是负面的。我们的研究结果表明，在寻求提高能源效率时，必须更仔细地考虑区域情况。
Improving energy efficiency is a highly effective policy for protecting the environment and preserving resources. Previous studies have measured energy efficiency in the industrial sector. We further contribute to understanding the factors that affect energy efficiency changes. This study measures energy efficiency based on plant-level data in Japan's paper/pulp and cement industries as representative energy intensive sectors. We analyze the relationship between the industrial agglomeration effect and the energy efficiency of each studied industry. Our results reflect several important findings. First, energy efficiency has improved in the paper and pulp industry as well as the cement industry between 2000 and 2010. However, the factors for improving energy efficiency differ between the industries. Second, industrial agglomeration affects energy efficiency. In the paper and pulp industry, the same industry agglomerations contribute to improvements in energy efficiency. However, the agglomeration effect is negative for energy efficiency in the cement industry. Our results indicate that one must consider regional circumstances more carefully when seeking to improve energy efficiency.
