【主题】Closing the Energy Efficiency Gap in Industrial Firms? The Role of Management Practices
We study the relationship between general and specialized management practices and energy use outcomes in machine components manufacturing firms in Shandong Province, China. First, we present results from a baseline survey that show electricity use intensity (either electricity expenditure or electricity use divided by output) declines as management score increases, consistent with studies in other settings. Second, we differentiate between general management practices and energy management practices, and show that firms that score highly on energy management also tend to have strong general management practices, but not necessarily the reverse. Third, in preliminary results from a randomized controlled trial, we find that external consultants were able to propose more recommendations on energy management and energy efficiency improvement to better-managed firms. Recommendations with relatively high standardization, not payback period per se, predicted adoption. We further find that treated firms show evidence of statistically-significant reductions in their imputed unit electricity price, but not in the quantity of electricity used. Our results thus far suggest that management practices may help firms to save cost but, in the absence of additional regulations, physical energy savings may be limited.
