This paper investigates the relationship between exports and economic growth in chinafor the reform and open-door period 1978-1996. The estimations presented indicate a positive andsignificant relation between the two variables. Also, the statistical adequacy of the models used issupported by several diagnostic test. The results provide support for the export-led growth (ELG)hypothesis.

The objective of this paper is to investigate the dynamic relationship between china′s trade balance (T) and macroeconomic variables: domestic and foreign output (Y and Y\+* ), real exchange rate (E), domestic and foreign money supply (M and M\+*). The ADF Unit root results show that the variables are all integrated of order I (1). The trade balance in china is not cointegrated with a number of variables, including the exchange rate. Absorption, elasticity, and monetary models are compared, and the elastic model performs better. There has been J\| curve in china, and the devaluations have had significant effect on the trade balance.

关键词： china′s foreign trade balance real exchange rate cointegration

This paper studies the performance of the GArCH model and two of its non linear modifications to forecast china′s weekly stock market volatility. The models are the Quadratic GArCH and the Glosten, Jagannathan and runkle models which have proposed to describe the often observed negative skewness in stock market indices. we find that the QGArCH model is best when the estimation sample does not contain extreme observations and that the GJr model cannot be recommended for forecasting.

The purpose of this paper is to investigate china′s state foreign exchange reserves growth using monthly data in the period January 1994 to December 1998. An economic model is constructed, with a view from its formation mechanism. Time series techniques are used to examine the long run relationship between foreign exchange reserves and the variables included in the model. Our empirical investigation revealed existence of a systematic long run relationship among foreign exchange reserves, exports, imports, and foreign direct investment. In the short run, the Asian financial crises have not significant effect on china′s foreign exchange reserves. Moreover, the recursive tests results indicated that the error correction model was structurally stable over the sample period, implying that the reserve holdings play a significant role in the balance payments adjustment process and separating china economy from the Asian financial crises.

研究了人工海水中三种金属离子K+,Mg2+和Ca2+分别在不同浓度下对冠瘤海鞘(Styelaca nopusSavigny)幼体附着和变态的影响,同时采用K+通道阻滞剂TEA检验其可兴奋细胞膜上的K+通道特性,对冠瘤海鞘幼体附着和变态的离子控制机制进行初步探讨,结果表明:K+的浓度为20~40mmol/dm3 时诱导幼体附着和变态的效果最佳,低于4 5mmol/dm3 和高于80mmol/dm3 的K+浓度都表现出抑制效果;Mg2+浓度在0 ~ 32 mmol/dm3 时显著促进幼体附着和变态,达88mmol/dm3时起抑制作用;在人工海水中无论添加或减少Ca2+,均有效抑制幼体变态.TEA不能阻抑增加K+的诱导作用,这表明冠瘤海鞘幼体可兴奋细胞膜上的K+通道对外部TEA不敏感.另外,人工海水中缺乏K+或Ca2+或K+浓度达80mmol/dm3 都会对冠瘤海鞘幼体产生毒害作用.

受国际金融危机影响,国际贸易保护主义抬头,中国遭遇反倾销形势严峻,严重影响中国的出口贸易。应用引入执行率、反倾销对称率及反倾销强度指数三个指标,从中国遭受反倾销及应对反击的总体特征、产品结构及其国别结构三方面进行了分析,发现国际金融危机下国外对华实行有针对性集中贸易反倾销攻击,借以转嫁国内经济危机,相对而言,中国没有充分对等地运用反倾销贸易保护手段。同时还提出相应的政策建议,以减少反倾销措施的不利影响。

科技进步是现代经济增长的推动力,而科技进步需要金融系统的支持。通过论证金融发展对科技进步的直接和间接作用机制,并对我国金融发展促进科技进步的影响进行实证研究,发现我国当前的金融体系不适合科技进步。而要使我国金融在促进科技进步上起到更好的作用,则必须健全完善的银行体系和建立多层次的资本市场。
