Energy saving technologies and productive efficiency in the Chinese iron and steel sector
Abstract: Energy saving and innovation are currently the subjects of much research. In this study we use the Cobb–Douglas (C–D) type production function to estimate the impact of energy saving technologies and innovation investments on the productive efficiency of Chinese iron and steel enterprises for the period 1990–2000. It is shown from the study results that some productive efficiency growth can be attributed to the adoption and amelioration of energy saving measures (pulverized coal injection technology, PCI; continuous casting technology, CCT) and the increase of technique updating and transformation (TUT) investments associated with energy saving. It is also found that the big enterprises possess a substantial efficiency advantage over small- and medium-sized steel makers. Finally, according to this study, enterprises in some certain locations may gain from the economies of agglomeration and hence perform better than others. The policy implications of this study provide an important rationale for the ongoing centralized merger campaign of the iron and steel industry in China. To accelerate the diffusion of advanced energy efficient technologies and encourage innovation will promote the productive efficiency.

Environmental Valuation & Cost-Benefit News
Environmental Valuation & Cost Benefit News covers legal, academic, and regulatory developments pertaining to the valuation of environmental amenities and disamenities, such as clean air, trees, parks, congestion, and noise. We apprise the reader about ways in which costs and benefits are measured, and the results of empirical studies. We hope that this information will allow public and private organizations to comprehend the risks and benefits of various actions, help disputants to resolve conflicts equitably and efficiently, and improve the quality of public policies. We will only discuss issues related to the empirical quantification of private and social costs and benefits and damages, and summarize information from daily newspapers, academic journals, legal publications, court decisions, professional newsletters commissioned studies, and on-line services. This newsletter is dedicated to the principal that all policies place values upon life, liberty, and the pursuit of happiness. We believe that more information, explicit specification of assumptions, and rigorous analysis can help our society to better meet these ends. This site will increasingly serve, in conjunction with others, as a valuation database. We will include a wide range of studies, including non-environmental reports, because omission of a factor effectively values it at zero, and biases decisions. Heavy traffic has caused several site crashes. We are attempting to correct these problems. Apologies for any inconvenience.
