中国企业“走出去”存在的问题及原因

近年来，中国不少企业已经走出国门，实施“走出去”的战略。但是从目前来看，还存在不少问题。主要表现在没有实现预期的目标、也没有给国家带来直接或间接的利益。出现这些问题的原因是中国企业竞争力还不强、投资犯有盲动的错误、违背经济规律。照目前的情形来看，中国的企业还不适宜大规模走出去。     

论水产企业“走出去”的贸易式模式——以湛江国联水产开发股份有限公司为例

水产业对外开放是渔业现代化的重要推动力量,水产企业"走出去"又是水产业对外开放的有机组成部分,中国水产企业如何"走出去"已成为当前中国水产业面临的一个重要课题。水产企业贸易式模式是水产企业"走出去"的一种重要模式。以湛江国联水产开发股份有限公司为例,对中国水产企业"走出去"贸易式模式进行了对比分析和评价,认为当前中国水产企业"走出去"模式主要依赖于贸易式模式。建议在以贸易式模式为主的同时,"走出去"模式应多样化;企业应根据国际化战略和动机,适时修正和选择"走出去"模式。

"走出去"信心不减脚步不停

金融危机给河南"走出去"的地勘单位带来新困难、新问题 近年来,河南省地矿局先后有15个局属单位进军20多个国家,截至目前已获取境外矿业权86个,项目涉及地质矿产勘查开发、工程承包、地质技术服务、加工制造等多个领域,外向型经济已占该局经济收入的近1/4.     

矿业“寒冬”,袖手还是出手?

<正>现在,全球的矿产勘探市场,已经到了退无可退,基本见底的状态。中国矿业"走出去",在历经波折之后,要发挥"屡败屡战"的精神,咬定目标不松口。上一轮"走出去"收获的教训,是再次征战海外的宝贵财富。冬天到了,春天还会远吗?此时此刻,应当该出手时就出手。2015年中国国际矿业大会有一个热点话题:值此矿业的寒冬,矿业市场触底了吗?在大会的"中国企业海外矿     

粮食安全背景下的中国农业跨国种植

农业对外开放是农业现代化的重要推动力量,农业“走出去”又是农业对外开放的有机组成部分,中国农业如何“走出去”已成为当前中国农业面临的一个重要课题.农业跨国种植是农业“走出去”的一种重要模式.在对国内外农业跨国种植历程和特点分析的基础上,从政府、企业、经济效益、政治因素等角度对中国农业跨国种植兴起的原因、障碍因素进行了剖析,总结了国内外农业跨国种植的经验及启示:重视土地使用权的获取,农业跨国种植应立足于带动国内要素输出,种植品种的选择可因“走出去”主体不同而有所侧重     

从2016中国国际矿业大会看中外矿业合作的现状与前景

正中国矿业企业已经开始进行全球范围内的矿业合作。正如一位业内人士所说:"在世界的每个角落都能看到中国企业,甚至在你想象不到的地方。"尽管有人质疑走出去的中国企业失败太多,但这也从另一角度说明,中国企业越发强大了。"谁也不是刚出生就会走路。成长总要付出代价,但同时也积累了经验。"不管怎样,我们终究是跨出去了。在这位业内人士看来,目前我们更需要做的是让企业规避风险,逐渐成熟,最终与投资所在国实现

河南地矿局非洲矿产勘查基地已形成

实施"走出去"战略,是党中央国务院在深刻分析国际国内政治经济形势基础上做出的重大决策.随着我国国民经济的快速发展,我国基础矿产原料日益缺乏,许多大宗矿产品呈现出危机趋势,给国民经济的可持续发展提出了严峻挑战.在此情况下,及时"走出去",勘查、开发国外矿产资源,积极开拓和融入海外资源市场,参与世界资源市场的竞争与再分配,已经成为我国新时期重要战略目标之,也是保障国家资源安全和长远发展的重要手段和根本需要.河南省地矿局认真贯彻落实中央和省委、省政府"走出去"战略部署,通过两年来的不断拓展,相继在非洲、南美和我国周边国家开展了系列地质与矿产勘查工作,非洲津巴布韦、阿尔及利亚、纳米比亚矿产勘查基地已基本形成,塞拉利昂、莫桑比克等矿产勘查工作也即将展开,矿产勘查"走出去"战略迈出坚实步伐.     

Preliminary study on plasma membrane fluidity of Psychrophilic Yeast Rhodotorula sp.NJ298 in low temperature

The ability of cell to modulate the fluidity of plasma membrane was crucial to the survival of microorganism at low temperature. Plasma membrane proteins, fatty acids and carotenoids profiles of Antarctic psychrophilc yeast Rhodotorula sp. NJ298 were investigated at -3 ℃, 0 ℃ and 8 ℃. The results showed that plasma membrane protein content was greater at -3 ℃ than that at 8 ℃, and a unique membrane polypeptide composition with an apparent molecular mass of 94.7 kDa was newly synthesized with SDS-PAGE analysis; GC analysis showed that the main changes of fatty acids were the percentage of unsaturated fatty acids (C18∶ 1 and C18∶ 2) and shorter chain saturated fatty acid (C10∶ 0) increased along with the decrease of the culture temperature from 8 ℃ to -3 ℃; HPLC analysis indicated that astaxanthin was the major functional carotenoids of the plasma membrane, percentage of which increased from 54.6±1.5% at 8 ℃ to 81.9±2.1% at -3 ℃. However the fluidity of plasma membrane which was determined by measuring fluorescence anisotropy was similar at -3 ℃, 0 ℃ and 8 ℃. Hence these changes in plasma membrane's characteristics were involved in the cellular cold-adaptation by which NJ298 could maintain normal plasma membrane fluidity at near-freezing temperature.

Sea ice thickness measurement in spring season in Bothnian Bay using an electromagnetic induction instrument

As an important component of the cryosphere,sea ice is very sensitive to the climate change.The study of the sea ice physics needs accurate sea ice thickness.This paper presents an electromagnetic-induction(EM) technique which can be used to measure the sea ice thickness distribution efficiently,and the successful application in Bothnian Bay.Based on the electromagnetic field theory and the electrical properties of sea ice and seawater,EM technique can detect the distance between the instrument and the ice/water interface accurately,than the sea ice thickness is obtained.Contrastive analysis of the apparent conductivity data obtained by EM and the value of drill-hole at same positions allows a construction of a transformable formula of the apparent conductivity to sea ice thickness.The verification of the sea ice thickness calculated by this formula indicates that EM technique is able to get reliable sea ice thickness with average relative error of only 12%.The statistic of all ice thickness profiles shows that the level ice distribution in Bothnian Bay was 0.4-0.6 m.     

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.
