摘要人们普遍认为，通过提高生产率和增强商业竞争力，技术现代化对经济发展以及环境和资源保护都有积极贡献。然而，这可能并不总是正确的，特别是在短期内，因为它需要大量投资，并可能给进行这种投资的公司带来财务负担。本文实证检验了上世纪90年代中国钢铁工业技术现代化对常规经济生产率和环境敏感型生产率的影响。我们采用了一个可以处理多个输入和输出的方向距离函数来计算相对生产效率。我们将这些模型应用于1990年至1999年中国的27家钢铁企业的数据，这段时期中国钢铁工业迅速现代化。我们发现，即使在CEP下降的时期，ESP也在不断改善。
ABSTRACT Technological modernization is widely believed to contribute positively both to economic development and to environmental and resource conservation, through improvements in productivity and strengthening of business competitiveness. However, this may not always be true, particularly in the short term, as it requires substantial investments and may impose financial burdens on firms undertaking such investments. This study empirically examines the effects of technological modernization in China's iron and steel industry in the 1990s on conventional economic productivity (CEP) and environmentally sensitive productivities (ESPs). We employ a directional distance function that can handle multiple inputs and outputs to compute relative production efficiencies. We apply these models to the data covering 27 iron and steel firms in China between 1990 and 1999 – a period when the Chinese iron and steel industry modernized rapidly. We find that ESPs have continuously improved, even in the period when the CEP declined.
