In these years, Chinese government executes expansionary fiscal policies in order to keep the economy growth at a stable rate. It is very important to study the validity of the fiscal policies, which will provide the theory and practice basis for continuing the expansionary fiscal policies. In this paper, we utilize the changes of the velocity of money to study the effectiveness of the fiscal policy in China. We find that the velocity of money present a downward trend from 1978 to 2001, but the downward trend slows down with the time going?We also find that the change of the velocity of money is positively relevant to the change of the fiscal expenditure. Making use of the estimate of the marginal propensity to consume and the mean value of the velocity of money, we measure the effect of changes of fiscal expenditure on the change of GDP, and conclude that the expansionary fiscal policies in China are effective. We also should point out that the growth rate of fiscal expenditure keep a upward trend since 1978, while the growth rate of the velocity of money present a downward trend since the 1990's, which will put great pressure on the economic growth of China.

最近几年,我国政府为了保持经济的稳定增长,实行了扩张性的财政政策。政府实行的财政政策是否有效,程度如何,对这个问题的研究将对未来几年我国是否应继续采取扩张性财政政策提供理论根据和实践依据。我们利用货币流通速度的变化来研究我国实行的财政政策的有效性问题,通过计算发现:1978—2001年期间我国货币流通速度呈下降趋势,但是下降趋势越来越缓慢;我国货币流通速度的变化同财政支出的增长变化方向相同。利用我国居民边际消费倾向的估计值和货币流通速度的平均值数据,我们度量了我国财政支出变化对GDP变化的影响程度,得出我国实行的扩张性财政政策有效的结论。但是必须要指出的是,从1978年以来我国财政支出增长率的长期趋势持续上升,而从90年代以后货币流通速度的增长率的长期趋势却下降,这将给我国的经济增长带来很大的压力。

Winter freezing damage data of 88 meteorological stations in Guangxi from 1960 to 2000 are analysed by methods such as natural orthogonal function development, linearity trend estimation, MannKendal and MHAT to study the temporal and spatial features, trend of change, mutation and periodicity of winter freezing damage in Guangxi. The result shows that there are 2 kinds of winter freezing damage distribution in Guangxi: 1) excessive (or fewer) damages in the whole region, 2) excessive damages in northeast area of Guangxi and part of the drainage areas while fewer in other areas. The stations that have records of winter freezing damage are on the trend of decrease. A point of mutation occurs around the year of 1985-1987, and its changing cycle is not obvious, but the changes among the years are great.

利用广西88个气象观测站1960~2000年冬季冻害站数资料,通过采用自然正交函数开展、线性倾向估计、Mann—Kendal、MHAT分析等方法,分析了广西冬季冻害的时空特征、变化趋势、突变、周期性。得出结论:广西冬季冻害主要有2种分布型态:(1)全区偏多(少)型;(2)桂东北及部分江、河流域偏多,其余偏少型。冻害站数呈减少趋势,在1985~1987年前后出现突变点,其变化周期不明显,但年际变化较大。

Based on the data of annual and seasonal mean air temperature,minimum and maximum air temperature and precipitation at eleven meteorological stations in Hainan Island from 1961 to 2002,the climatic change of Hainan Island is analyzed. The linear trend estimation indicates that annual mean temperature,minimum and maximum temperature have an evident warming trend,especially the mean minimum air temperature. Except winter precipitation appears to be an evident increase trend,the other seasonal and annual precipitation appear to be a weak increase trend in the region. The precipitation of the south part appears to be an evident increase trend,the other regions appear to be a weak increase/decrease trend. Mann-kendall analysis shows that from the end of 1970's to the end of 1980's,annual mean and seasons air temperature appear to be a transition,the warming was more evident since 1980's. The periodic analysis shows that the main period of temperature and precipitation are about 2-to 5-year and 7-to 11- year.

利用 1 96 1~ 2 0 0 2年海南岛 1 1个气象站各季和年的平均气温、平均最高气温、平均最低气温、降雨量等资料 ,对海南岛近 4 2年的气候变化作了较全面的分析。线性倾向估计表明 :季和年的平均气温、平均最高气温、平均最低气温具有显著增温趋势 ,特别是平均最低气温尤其显著。从全岛平均情况看 ,降雨量除了冬季有明显增加趋势外 ,其余各季和年的降雨量仅有弱的增加趋势 ;从各地区看 ,仅南部地区降雨量有显著增多趋势 ,其余地区各季呈弱的增加或减少趋势。Mann Kendall检验表明 :从2 0世纪 70年代末到 80年代末 ,各季和年的气温要素几乎先后发生了突变 ,80年代至今海南省进入明显的暖期。周期分析显示 ,各研究要素基本具有准 2~ 5年和准 7~ 1 1年的周期。
