Our study proposes to capture the heterogeneities and estimate the energy efficiency, technology gap and CO2 performance of enterprises in Guangdong province. We employ group-frontier and meta-frontier directional distance function to analyze the technical efficiency based on the groups categorized in terms of both geographical boundaries and industrial classification system. The estimation indicates that high developed regions are technical efficiency compared to the others, but they still have the largest potential to contribute to CO2 reduction. Technical efficiency of enterprises in middle developed regions is dispersing and CO2 emission can be further reduced by 3.38% in this region. Furthermore, many enterprises belonging to the industries with high efficiency still have huge technology gap reaching 0.66 (mental manufacturing), and it also potential to improve their energy and CO2 performance individually. Enterprises belong to inefficient industry can contribute to CO2 reduction via macroeconomic measures. Key words: energy efficiency; technology gap; CO2 reduction; enterprises; meta-frontier directional distance function
