贸易战背景下中国—巴西贸易摩擦分析及对策

随着全球经济一体化程度的加深,我国和巴西的贸易联系越来越紧密,但两国的贸易冲突也在不断加大。究其原因,既有全球经济周期性低迷的因素,也有两国自身的因素。分析两国贸易摩擦的原因,提出对策建议,如推进外贸企业转型升级,利用好资本红利,充分发挥行业协会和跨国公司的优势等。

Comparison of Corn Production Costs in China,the U.S. and Brazil and Its Implications

This paper analyzes the corn production cost in China, the U.S. and Brazil from 1997 to 2014. According to the results,（1） corn production cost in China is the highest among these three countries;（2） the rapid growth of labor cost and land cost is the major factor that promotes the increase of total corn production cost in China;（3） the level of agricultural mechanization in China has been gradually improving, and the gap between agricultural mechanization levels in China and other two countries is constantly narrowing;（4） differing from the U.S. and Brazil,China exhibits a ＂high input, low output＂ agricultural production mode. Based on the above analyses, corresponding suggestions have been presented to reduce corn production cost in China.

Perspectives of the Brazilian Poultry Industry for the Chinese Consumer Market

The objective of this article was to analyze the poultry and derivatives commerce between Brazil and China, taking into account the current market and the perspectives for the next years. The method used was the bibliographic review and analysis of secondary data from different sources, associated with the Market Orientation Theory and the Value Chain Theory. Nowadays, China is Brazil＇s main commercial partner in the international market, but taking into account the chicken meat and its derivatives, having Brazil as the first worldwide exporter and China, the second largest consumer, an effective commercial relationship has not been established yet. To understand the poultry market exchanges between Brazil and China, a framework was built to demonstrate the characteristics and factors found to influence country negotiations, considering current reality and future perspectives. Considering the Theory of Market Orientation, it is concluded that Brazil has effective conditions to consolidate itself as a major supplier of chicken meat and derivatives to China, because it shows determinant characteristics and market factors that allows the association of the national poultry value chain to the demands of the Chinese consumers, but some adjustments are needed in the sphere of international politics.

Geomorphological Evolution Revealed by Aeolian Sedimentary Structure in Badain Jaran Desert on Alxa Plateau, Northwest China

The Badain Jaran Desert,located in the Alxa Plateau,Northwest China,features mega-dunes and a unique dune-lake alternation landscape.This paper presented the aeolian sediment structures of three representative dunes in the Badain Jaran Desert using ground-penetrating radar (GPR).We processed and analyzed the GPR data and investigated the feasibility of using integrated GPR and sedimentological data to reconstruct dunes structure,sedimentary environment and geomorphological evolution.The results show that the internal structures of star dune and transverse dune represent various stages of mega-dune evolution: the main deposition processes of mega-dune are similar to those of transverse dunes but have a more complicated mechanism of sand transport and deposition because of the superimposition of dunes;the upper section of the mega-dune has a structure similar to that of star dune,with vertical aggradations on top.Diffraction hyperbolae in the GPR profile indicates that the presence of ancient dunes characterized by calcareous cementation layers is involved in the maintenance of mega-dunes,and water levels,shown by continuous,sub-horizontal GPR reflections,are supposed to be closely related to mega-dunes and the interdune lakes.Outcrop of wet sand and horizontal stratifications on the GPR image indicate moisture potentials with different levels inside mega-dunes.The multiplex geomorphology in the Badain Jaran Desert is the result of global climatic undulation,the unique geographical location,the geological structural features,etc.

Cosmopolitan Temporalities： A Sociological Analysis on Climate Imageries in Brazil and China

Time is a central theoretical resource for climate change science, climate policies, social actions addressing climate change problems, and shaping concepts of uncertainty and ambiguity. This paper presents a debate on how different epis- temic climate science communities deal with the concept of time by considering the social construction of climate imageries. To do so, we undertake two case studies on how China and Brazil＇s climate communities have shaped situated knowledge based on different historical social experiences that created different modes of dealing with climate change： China has created a concept of time based on practical climate experiences, while Brazil has developed a futuristic sense of how the climate will behave in the future. Finally, we address the idea of cosmopolitan climate imageries originated from hybrid forums and constructed by stocks of knowledge which have been shared transhistorically by different epistemic communities towards a common climate governance.
