Businesses aim to make profit, but very often they fail to take environmental protection into consideration in the drive to please stakeholders. In this article, a new conceptual framework for evaluating corporate integrated development through the perspective of efficiency (looking at the company's work value created in terms of input-output) is introduced. Under the proposed framework, businesses, investors and society can conveniently understand and evaluate corporate holistic performance including its operational competence, financial health and environmental friendliness. Therefore, decisions of different levels and groups could be made with programmed consideration on this purely analytical ground. Copyright (c) 2005 John Wiley & Sons, Ltd and ERP Environment.

A country's macroeconomic policies have two basic objectives: to provide its citizens with a means to make a better living and a preferable environment. For the past decades, accompanying its fantastic economic growth, fast-developing Asia has become one of the major contributors to the increase of global carbon dioxide emissions. This paper analyzes productivity growth of ten Asian countries, namely, China, Japan, the NIEs and the ASEAN-4, by examining their outputs from economic performance and environmental impact standpoints. Productivity growth and its components are calculated using the Malmquist index. There appears to be a widening gap between the productivity growth trends without/with CO2 emissions of the ten Asian economies. This implies that the factor of productivity could be over-emphasized at great cost to the environment. A cross-country comparison analysis, considering CO2 emissions, shows that the productivity of China and ASEAN-4 deteriorated while the productivity growth of Japan and NIEs performed much better.

Producing impurity-doped diamond films is a critical task for modern electronic applications. In this study, the effects of phosphorus in the gas phase on the morphological features of polycrystalline diamond films were investigated. The diamond films were prepared on n-type Si(100) substrates by the microwave plasma chemical vapour deposition. A trimethyl-phosphite vapour was introduced to the CH4-CO2 gas mixture as a dopant source. Surface morphology changed from well-defined facets to ball-like features by increasing the dopant concentration in the gas phase. Phosphorus-doped diamond films of good quality and well defined facets could be obtained by reducing the carbon concentration of reactant gases. This reduction could be achieved by decreasing the CH4 flow rates during the deposition process. An increase in the the dopant source caused the growth rate to become lower, the nucleation density to reduce drastically, and the relative intensity of XRD characteristic (110) peak to increase significantly.

China has seen rapid economic growth over the past two decades, but severe environmental problems have accompanied this, such as the looming danger of Asian Brown Clouds. This paper analyzes the regional development of China by examining economic performance and environmental factors. Technical efficiency and productivity changes in 31 regions of China are computed for the period 1997-2001. In the case of regional GDP, the fast-developing eastern (coastal) regions experience higher technical efficiency and productivity growth than the inland central and western regions. When environmental factors are incorporated, the eastern regions still perform better than inland regions, both from static and dynamic analysis. This phenomenon is termed the 'double deterioration' of the inland areas in China. Double deterioration is attributed to the lack of economic resources to replace highly-polluting production equipment and technology in those less developed regions.
