Conduction pathways of resource endowment affecting carbon intensity:Based on interprovincial data in China

By establishing a mathematical model and a basic analytical framework for the impact of resource endowments on carbon intensity,a traditional panel model without spatial panel effects was firstly constructed,a Durbin-Wu-Hausman test was conducted,and the model was set as a fixed-effects model based on the statistical values;secondly,the traditional panel model without spatial effects was estimated,and LM tests and robustness tests were conducted on the regression residuals.The LM test was then used to remove the fixed effect terms by the de-meaning method,and the Matlab 7.0 software was used to estimate the model.The stepwise introduction of variables was used to observe the effect of each variable on economic growth and to analyze the relationship between the magnitude and significance of the regression parameters of each variable.Finally,the path of conduction effect of resource endowment through mediating variable sinfluencing economic growth and carbon emissions,and thus carbon intensity,was constructed.The conclusion is that carbon intensity is inversely proportional to economic growth for a given level of carbon emissions.Therefore,if resource endowment promotes economic growth through mediating variables,it will lead to a decrease in carbon intensity,which is conducive to the achievement of emission reduction targets;conversely,if resource endowment hinders economic growth through mediating variables,it will lead to an increase in carbon intensity,which is not conducive to the achievement of emission reduction targets.

Application of the Concept of“Endowing the Old with the New”in Urban Renewal

The renewal of ancient cities is an important part of the urban renewal work in China.However,there are few studies on the general historical ancient cities at the county level in China,and there is no guidance on the renewal path.Through the practice of the renewal design project of Suining County,Xuzhou City,it makes an exploratory study on the renewal concept and mode.It first interprets the connotation and implementation path of the renewal concept of“endowing the old with the new”.Based on the texture analysis of the ancient city of Suining,it finally determines the design theme that tracing the historical context of the ancient city.Using the renewal techniques such as“extraction-transformationactivation”,through the renewal strategies such as“building new space,shaping new landscape,inheriting new culture and pregnant with new environment”,it realizes the regeneration of urban historical context and meets the needs of residents'modern life,so as to provide reference and guidance for the renovation of general historical ancient cities at the county level in China.

Current Situation and Demand of Rural Endowment Security in Shaanxi Province

With intensification of population aging and rise in elderly dependency ratio,the demand for endowment security becomes higher and higher,particularly in rural areas.Taking Shaanxi Province as an example,the authors selected people older than 65 in 18 natural villages in north Shaanxi,south Shaanxi and Guanzhong.With the aid of survey data and related official statistical data,they made an evaluation of current situation of the rural endowment security in Shaanxi Province.Results indicate that home-based endowment is the major endowment method of rural elderly,but such method is influenced by family's economic support ability and children's support willingness,thus facing big demand gap.On the basis of analyzing gap problem,the authors recommended that government should increase financial and policy supports,optimize management and monitoring,actively develop non-government organizations,and promote socialization of rural endowment service.

Analysis on the Optimization of New Rural Social Endowment Insurance in Changsha,Zhuzhou and Xiangtan

On the basis of the investigation on the status quo of pilot area of rural endowment insurance in Changsha,Zhuzhou and Xiangtan,farmers' demand on insuance in the new pilot area of rural endowment insurance is expounded from two aspects:farmers' awareness on insurance is increasing gradually;farmers' ability on insuring is increasing.The growing demand of farmers on insuring and the conflicts between the supply of rural endowment insurance and the system construction are analyzed.The problems are inadequate input of funds,low level of social security;imperfect fund-collecting mechanism,serious vacancy;low level of fund management and operation,poor ability of inflation-proofing and appreciation;backward laws and regulations and instability of system.On the strength of the analysis above,the government should innovate and compound fund-collecting mechanism;establish "G-C-F" three-pillar model and set up "BSI" the third party custodian;accelerate the legislation of new rural pension system so as to push forward the optimization of new rural pension insurance system in Changsha,Zhuzhou and Xiangtan.

Farmers' Land Transfer-out Behavior from the Perspective of Household Livelihood Endowment Based on the Survey in Anhui,Hubei and Sichuan

Based on the household livelihood endowment theory and the survey of 367 farmer households in Anhui,Hubei,and Sichuan in 2016,and using the orderly multi-category logistic model,the behavioral decision of farmers in the land circulation was discussed to explore the key parameters influencing the land transfer-out. It found that decisions of farmers on land transfer-out behavior are affected by many factors.Specifically,household non-agricultural income and per capita land area significantly reduce farmers' willingness to transfer land,while the household head age,agricultural input-output ratio,and confirmation of land right significantly promote the farmers' decision on land transferout. Therefore,increasing the allocation efficiency of household livelihood endowment has important policy value and practical significance for eliminating unreasonable land circulation and promoting large-scale agricultural production.

Efficient catalytic removal of COS and H_(2)S over graphitized 2D micro-meso-macroporous carbons endowed with ample nitrogen sites synthesized via mechanochemical carbonization

Developing a suitable catalyst for the elimination of highly toxic carbonyl sulfide(COS)and hydrogen sulfide(H_(2)S) is of great significance in terms of industrial safety and environmental protection.We demonstrate here the facile synthesis of graphitized 2D micro-meso-macroporous carbons by one-step carbonization of a mixture of urea and glucose at 700–900℃.The as-synthesized graphitized catalysts,designated as 2DNHPC-x(x=urea/glucose mass ratio),are endowed with an ultra-high concentration(12.9–20.2 wt%)of stable and versatile nitrogen sites(e.g.pyrrole and pyridine)which are anchored on the surface via stable covalent bonding.As a result,the 2D-NHPC-x are active in catalytic hydrolysis of COS on pyrrolic N to H_(2)S,and the H_(2)S can be subsequently captured on pyridinic N and converted to elemental sulfur at ambient conditions over the same materials.Among the prepared catalysts,2D-NHPC-x can catalytically hydrolysize 91%of COS to H_(2)S at 30℃,whereas the conversion ratio over the common catalysts g-C_(3)N_(4)and Fe_(2)O_(3)are below 6.0%.Furthermore,these catalysts also exhibit H_(2)S conversion and sulfur selectivity of nearly 100%at 180℃with long-time durability,which is higher than those of the most reported carbonbased catalysts.In contrast,the H_(2)S capacities of activated carbon,ordered mesoporous carbons(OMC)and N-doped OMC are 3.9,1.5 and2.39 mmol g^(-1),respectively.Both the experimental and theoretical results are disclosed that 2D-NHPC-x are superior to the nitrogen-doped porous materials ever applied in simultaneous catalytic elimination of both COS and H_(2)S.

Gardaneh Salavat porphyry copper system: Is it about metal endowment or fertility of the porphyritic intrusion?

Gardaneh Salavat porphyry copper system is located in the northwest of Iran. It comprises a quartz diorite to diorite porphyritic intrusion that created extensive alteration haloes in the host rocks. Despite all technical considerations, the exploration activities did not yield to ore discovery. As the matter of fact, all of the geological,geophysical, and geochemical characteristics of a porphyry Cu-Au deposit exist but there is no economic mineralization. Detailed examinations suggest that the only reasonable explanation can be related to the infertility or low metal endowment of the porphyritic intrusion. The reasons include(1) anomalous ranges of Cu, Au, and Mo rather than economic ore grades,(2) weakly development of potassic alteration,(3) probably sulfur saturation of magma that occurred before intrusion emplacement in the host rocks, and(4) probably low metal endowment in the regional scale and the lack of known porphyry copper deposits in close neighborhoods. It is tried to test the proposed hypothesis with the introduced fertility indicators based on major and trace element geochemistry. However,current fertility indicators could not prove or reject the proposed hypothesis for Gardaneh Salavat porphyritic intrusion because of the high-K calc-alkaline to shoshonitic nature of the intrusive rocks together with the unavailability of relatively fresh/unaltered samples. This case study is notable to examine because(1) it shows that characterization of fertile from barren intrusions seems to be as important as vectoring towards concealed porphyry copper deposits, especially while dealing with deep exploration targets that are associated with high financial risks, and(2) it highlights the inefficiencies and uncertainties in introduced magma fertility indicators for porphyry copper intrusions. As a result, it is of high importance to conduct an overarching investigation on other possible fertility indicators as a fundamental need for the future of the exploration industry.

Through the deep investigation of residential districts, the paper explored the community endowment mode that is between the organization support and home-based care for the aged, and proposed 3 modes on the basis of "visiting, day care and short-stay". Considering the specific needs of the aged and the compound modes, compound community endowment mode was put forward as the future development direction of community endowment to contribute to the construction of the overall social endowment system.

Relationship between Economic Development,Resource Endowment and Soybean Export Dependability

The dependability of world major soybean exporters was measured and its influencing factors were analyzed through constructing the export output elasticity indicator.It was found that since 2010,among the world major soybean exporters,the dependability of Brazil,India,Russia and Ukraine increased,the dependability of Argentina and Paraguay dropped,while that of Canada,the USA and Uruguay was basically stable.Among the influencing factors of the dependability,the increase in international soybean prices and abundance of cultivated land resources are helpful for increasing the dependability,while the increase of population and improvement of economic development will reduce the dependability.China should reduce its dependence on countries with low export dependability,and actively develop production cooperation with import source countries to promote their dependability.

Research on the moderation of endowment insurance in Shanghai

Old-age insurance is related to the quality of life of the elderly population in a country or region after retirement, the impact of economic crisis and the aggravation of the population aging crisis, so that the appropriateness of the level of old-age insurance has been paid more and more attention by the society. At present, the academic research on the appropriate level of endowment insurance is still at an exploratory stage. Most scholars mainly study the endowment insurance from the qualitative point of view, but lack quantitative analysis of the level of endowment insurance. Pension expenditure must be in line with the level of national productivity development and various aspects of affordability. Shanghai is the fastest growing city in China and the earliest city in China to enter an aging society. It is of typical significance to study the appropriateness of the endowment insurance level in Shanghai.

An Empirical Study on the Effects of Social Endowment Insurance Reform in China

In recent years,China,the world’s largest population country,has also become an aging society.Social endowment insurance is not only a major source of income after retirement but also plays a major role in social stability.In 2005,large-scale social endowment insurance reform was conducted in China.Through this reform,the social endowment insurance became unified and normalized,and the participation of the social endowment insurance was obligated for an employee.In addition,the government has issued various welfare policies so that the unemployed,free job and rural residents can join social endowment insurance.Then,this paper analyzes the effect of the reform of China social endowment insurance on the amount of Insurance premium of social endowment insurance and the distribution of family expenditure by using the DID model and the fixed effect model.

Legal Origin, Endowment and Financial Development
