缺乏优势企业的跨国经营战略

本文从技术外溢、尾随优势和干中学效应角度出发,建立假设模型来论证缺乏优势企业为了技术获得而对外直接投资的理论依据,并指出其与传统跨国企业经营理论的关系,最后提出政府主要相关的扶持措施

The Study of Industrial Cluster and the Economy Development of the Developing District

地区间发展不平衡始终是我国经济发展中的一个重大议题，改革开放以来，政策的倾斜和市场机制的“马太效应”，加剧了区域经济发展水平的差距。因此，如何消除弱势，缩小差距，迅速提升区域竞争力，不仅是欠发达地区现阶段的任务，也是欠发达地区的必然选择。产业集群模式作为新型工业化得以实现的重要载体，对促进欠发达地区加快发展，逐步解决发展的不平衡问题具有重要意义。本文以马克思主义经济理论方法为指导，在系统地分析了欠发达地区经济发展的现状和总结前人产业集群的研究成果的基础之上，提出欠发达地区的经济发展完全有可能借助产业集群模式，通过政府扶持、市场培育和企业创新，进一步增强区域经济的综合竞争力，实现跨越式发展。全文...The unbalance development between different areas is always a big issue for China economy development. The inclining policy and the “Mattew Effect” of market mechanism enhances the disparity of economy developing level .So how to eliminate the gap and increase the district competitive power is not only the responsibility of the developing district but also its inevitably choice.

Evaluation on difference of therapeutic efficacy of Jiawei Xiaoyao Granules and Pills in treatment of emotional disorder during perimenopause based on Greene Climacteric Scale

目的:在前期加味逍遥丸治疗围绝经期情绪障碍具有比较优势的基础上,基于grEEnE量表探讨其颗粒剂和丸剂不同剂型间疗效差异。方法:经筛选后患有情绪障碍的围绝经期女性75例随机等分为A、b、C3组,分别对应采用帕罗西汀、加味逍遥丸和加味逍遥颗粒剂治疗8周。所有患者在治疗前后各进行1次grEEnE及其子因子评定,并在观察期结束时进行TESS评定。结果:grEEnE总分差及其焦虑、抑郁因子分差:3种治疗方法均能改善,且相互间无显著差异;grEEnE性因子和血管因子分差:后二组均优于A组(P<0.01);TESS评分:与A组比较,b、C组均有统计学意义(P<0.01),评分均小于A组,且后二组间无显著差异。结论:加味逍遥的2种剂型间疗效无显著差异,考虑到帕罗西汀的不良反应,治疗该病加味逍遥的2种剂型都值得推荐。Objective: To investigate the difference in therapeutic efficacy between Jiawei Xiaoyao Granules and pills based on the preliminary research of treating emotional disorder during perimenopause with Jiawei Xiaoyao Pills and Greene Climacteric Scale.Methods: 75 female patients with emotional disorder during perimenopause were slected and randomly divided into 3 groups as group A, B and C.Patients in the 3 groups were treated with paroxetine, Jiawei Xiaoyao Pills and Jiawei Xiaoyao Granules respectively for 8 weeks.Greene and Greene factors assessment were carried out in all the patients before and after treatment, and the TESS assessment was carried out at the end of the observation period.Results: The three therapies all could improve the gap in total score of Greene and its factors as anxiety and depressed, and the difference among these three groups was no significant.The factors of Greene and gap in score of vascular factors of group B and C was better than that of group A(P<0.01).The difference in TESS score between group A and group B and C was significant(P<0.01), while the difference between group B and group C was not significant.Conclusion: The difference in curative effect between the two formulations was not significant.Because of the adverse reactions of paroxetine, in the treatment of emotional disorder during perimenopause, the two formulations of Jiawei Xiaoyao Powder were worth to be recommended.国家自然科学青年基金项目(No.81302960)~

新疆干旱区绿洲可持续发展水平及其空间分布特征

本文选取经济、社会、生态环境三方面22个与新疆干旱区绿洲可持续发展密切相关的原始指标,通过因子分析对原始指标进行降维处理,得到7个综合指标。分别计算新疆87个市县的综合得分,并对其可持续发展能力进行排序。新疆可持续发展主因子存在明显的空间差异,且分化比较明显,形成北疆可持续发展水平较高,南疆相对较低的格局。在石油资源丰富且已大规模开发的市县和位于交通枢纽和交通干线上的市县,可持续发展的水平比较高

PREPARATION AND ELECTROCHEMICAL PROPERTIES OF CARBON NANOSPHERES FROM CaC2 - CCl4 SYSTEM

以碳化钙和四氯化碳为碳源,反应物通过无机化学反应在密封高压釜中制备了纳米碳球。用XRD、SEM、EDS、TEM、HRTEM和BET法对碳球的形貌和结构进行表征,并采用恒流放电法研究其作为锂离子电池负极材料的电化学性能。研究结果表明:合成的纳米碳球具有棉花状结构,直径分布为80～250nm,其d002为0.336～0.340nm,属于无定形碳结构,BET比表面积为98m2/g。纳米碳球作为负极材料首次充放电比容量分别为787mA·h/g和390mA·h/g,充放电效率为49.6%;5次循环后放电比容量衰减到239mA·h/g,但效率均保持在95%以上。Carbon nanospheres were synthesized by an inorganic chemical reaction with calcium carbide and chloroform as carbon sources in a sealed autoclave. The morphology and microstructure of the carbon spheres were characterized by XRD, SEM,EDS, TEM, HRTEM, and BET specific surface area, and the electrochemical properties of the carbon spheres as anode material for lithium- ion batteries were investigated by use of chronopotentiometry （CP） . The results indicate that the carbon spheres are composed of the cottonstructure spheres with the diameter between 80 nm and 250 nm. The d002 of the carbon spheres are in the range of 0. 336 ～0. 340 nm and the BET area surface is 98 m2/g. The first charge/discharge specific capacities of the carbon spheres as negative electrodes are 787 mA·h/g and 390 mA· h/g, respectively, and the first efficiency is 49. 5%. After 5 times cycles,the discharge specific capacity decreases to 239 mA· h/g,but the efficiency keeps above 95%.国家重点基础研究发展计划(973计划)资助项目(2006CB600901
