Research on Resources and Environmental Carrying Capacity

This paper, in the context of resources and environmental carrying capaci-ty, systematic reviewed resources and environmental carrying capacity in monitoring, evaluation and early warning, and then putted forward the development direction for promoting the sustainable development of China’s social and economic environment.

The theory and method research on the double evaluation of land and space:A survey

By reviewing the theories and methods of resource and environmental carrying capacity evaluation and suitability evaluation of land and space development,it provides theoretical and technical support for rational layout and optimization of land and space development pattern.From the aspects of resource carrying capacity,environmental carrying capacity,the importance of ecological protection,the suitability of agricultural production,and the suitability of urban construction,we sort out domestic and foreign documents.The evaluation of resource carrying capacity has changed from single-factor evaluation to multi-factor comprehensive evaluation.At present,the optimization of land use pattern based on the“three-generation”space is still under exploration,it is not enough to systematize and summarize the thought of optimizing the spatial pattern of the national territory.The theoretical framework,model,method and index of“dual evaluation”of territorial space need to be improved continuously,it also needs the scientific analysis and cognition from the natural direction to the human location direction and the spatial equilibrium state as the new driving force.

Economic sustainability of China's growth from the perspective of its resource and environmental supply system:National scale modeling and policy analysis

Since the implementation of the economic reform and opening up policy in 1978,China has miraculously created long-term high-speed economic growth,but has also had to face the problem of excessive consumption of resources as well as an intensification of environmental pollution.As a result,China is now facing a slowdown in development.China must maintain a certain speed of development to realize its goal of being a powerful nation,and becoming a developed country by 2050.To this end,China is facing a transformation of its economic development.There is a need to agree on an expected economic growth rate,along with the corresponding development modes or means of regulation in the medium-and long-term periods.This study developed a systematic-dynamic model to simulate the coupling relationship between economic growth,development modes,and the environmental supply system,and explored the possible options for future economic growth as well as the resource use and environmental protection requirements(the main factors).The results showed that to achieve the development goal of becoming a developed country by 2050,while maintaining a good ecological environment,the suitable growth rate for China's economy is 3.8%–6.3%.Within this range,a growth rate of 3.8%–4.4%was found to be relatively safe,while a growth rate of 4.4%–6.3%required further technical progress.This study provides an early warning in regard to China's environmental and development status.The study was a response to the"Future Earth"framework document and,in terms of development speed,it developed a theoretical system for the determination of resource and environmental carrying capacity(RECC).

Measuring the Effect of Foreign Direct Investment on CO2 Emissions in Laos

This paper aims to explore the determinants of C〇2 emissions in Laos by accounting for the significant role played by foreign direct investment(FDI)in influencing C 02 emissions during the period 1990-2017.We apply a Johansen co-integration testing approach to investigate the presence of co-integration,and the empirical findings underscore the presence of a long-run co-integration relationship between CO2 emissions,FDI,per capita GDP,and industrial structure.We also employ an error-correcting model to examine the short-term dynamic effect of FDI on CO2 emissions.The empirical results show that FDI has a significant short-term dynamic effect on changes in CO2 emissions,indicating that the relationship between FDI and CO2 emissions is an inverted U-shaped curve.This is a validation of the EKC.Changes of FDI,per capita GDP,and industrial structure increase CO2 emissions.Based on the analysis results,this paper puts forward policy suggestions emphasizing the need for both Laotian policymakers and Chinese investors to improve eco-environmental quality.
