In this paper, the authors analyze the annual rate of carbon productivity growth, the differences of carbon productivity of different countries, and the factors for enhancing carbon productivity. Consequently, the authors clarify their viewpoint that the annual rate of carbon productivity growth can be used to weigh the efforts that a country takes to address climate change, and propose policies and suggestions on promoting carbon production.展开更多

This is accomplished by using cross-country time-series data for a total of 70 developed and developing countries for the period from 2003 to 2008. The study reveals that the existence of causality and its direction differ across different income-group of countries and over the number of lags included. ICT investment expenditure as a percentage of GDP appears to cause the rate of growth of GDP per capita for the high income group and all income groups combined with lags higher than one year. However, for the upper- and lower-middle income groups, the study detects causality in neither direction. Also, when only one lag is included, the study suggests no causality in either direction for any of the income-groups of countries.展开更多

Correspondingly, the production would be constrained by the scarcity of resources clearly. Then the economic researchers would pay much more attention to reducing the consumption of natural resources in the future. Therefore this paper brings foreword the conception of elasticity ratio of resource consumption based on the concept of elasticity and analyzes the relationship between the parameters. For the certain relationships between the elasticity ratio of resource consumption and resource consumption, this paper will try to reveal, to keep economy growing while resource consumption reducing, what conditions should be met as to the relationships among resource productivity, its growth rate, energy saving efficiency, economic growth rate and elasticity ratio of resource consumption. This paper proves the relationship between the China＇s energy consumption and economy growth using statistic data from 1978 to 2003.展开更多
