It is an inevitable requirement to modify human development index (HDI) with greenness and fairness indicators. Using ecological footprint, this paper tried to construct the human-ecological sustainable development index (HEDI) based on panel data of 28 countries from 1990 to 2014, and analyzed the contribution of sub- indicators to HEDI with the Logarithmic Mean Divisia Index (LMDI) decomposition approach. Fairness was adjusted to construct a comprehensive human- ecological sustainable development index (cHEDI) that could fully reflect the degree of economy, society, ecology and equal development comprehensively. We analyzed the spatial and temporal changes of HEDI and cHEDI with the index in 28 countries around the world. The results show that developed countries with high biomass surplus are highly sustainable, ranking higher than other countries. One of the main factors affecting sustainable development is high carbon emissions in these countries. Besides the high carbon emissions, the shortage of biomass resources is another unsustainable reason in the developed countries with biomass deficit, which maintain development by transferring assets from other countries. Unfairness leads to a decline in comprehensive sustainability in the United States. From 1990 to 2014, income and education in developing countries increased rapidly, but ecological consumption and Gini coefficient continued to rise, and the inhibitory effect gradually expanded to increase the unsustainability of development. The sustainability index of the United States and developing countries is greatly affected by the Gini coefficient. The United Arab Emirates ranked last in the world, with the least sustainable development mode. Although its income ranked first in the world, biomass and energy consumption was very high, and the Gini coefficient far exceeded that of other countries. The development of the least developed countries mainly came from contribution of health, education and low ecological consumption. Barren natural assets limited their further development. Different countries have different shortcomings in human sustainable development. The sub- divisions were highly correlated, hence to achieve the high level of human sustainable development requires better balance between society, economy, greenness, and fairness.

Currently, low utilization ratio of science and technology resources has to be an important restriction factor that affects the development of science and technology in our country. It is necessary to establish and perfect the government-dominated paUern of sharing science and technology resources for realizing sustainable development. This paper, learning from the experience for science and technology resources sharing in some western developed countries, that contain the United States, European Union and Japan, studies the key problems in the development of science and technology resources sharing. Based on this analysis, some useful policies and suggestions, ranging from sharing strategy, sharing platform, management system are proposed. These conclusions are useful for the government to develop science and technology resources sharing. [ABSTRACT FROM AUTHOR]
