Abstract:

We investigate the relationship between general and specialized management practices and energy use outcomes in a machine components manufacturing cluster in Shandong Province, China. We conduct an on-site survey of 100 firms that combines the core questions from a survey of general management practices with a new questionnaire on energy management practices, and separately collect three years of firm energy use data. Moving from the 25th to 75th percentile on management score is associated with a reduction in electricity intensity of 17% in value terms (electricity expenditure divided by output value) but only an 8% reduction in physical terms (electricity use in kilowatt-hours divided by output value). Energy management score is found to increase with general management score, and large firms tend to score highly on both measures. Interest in adopting an energy management tool increases with energy management score, while overall management score only weakly predicts interest. Modern management practices may enable organizations: 1) to identify and deploy interventions (such as load shifting) that translate into cost savings and 2) to develop specialized management practices (in this case, for energy), which in turn may increase capacity to absorb information that is of potential but uncertain value to the firm.

我们以一批中国山东的机械加工企业为研究对象,探索了企业的管理和能源管理水平与能效之间的关系。我们通过管理和能源管理调查问卷,获得了100家企业管理和能源管理水平信息,并获得了它们的用能数据。我们发现,管理水平从25百分位数提升到75百分位数, 电力强度(按价格计)将下降17%,电力强度(按物理量计)将下降8%。企业的能源管理水平和管理水平存在正相关关系,较大规模一般会有较好的企业管理和能源管理水平。我们还发现能源管理水平较高的企业更有兴趣了解采用外部的节能建议。因此,现代管理对于企业节能的作用一方面在于使得企业更好挖掘类似于负荷转移的节能机会,另一方面也让企业更开放的接受外来节能建议。
