| 摘 要： | 同步性是我国生猪生产波动的重要特征之一.利用相关系数法和同步系数法,结合1952-2007年年末生猪存栏量数据,对陕西与全国生猪生产波动的同步性特征进行了比较分析.结果显示:同步系数法的测度结果比相关系数更科学；陕西与全国生猪生产波动的同步性程度达到0.763 6,且这种同步性具有越来越强的变化趋势；以陕西省作为全国生猪生产波动的一个观测点,分析全国生猪生产波动趋势具有一定的科学性.

| Abstract: | Co-movement is one of the important characteristics of hog output fluctuation.This paper studies the co-movement characteristics of production fluctuation between Shaanxi and China by using correlation coefficient and simultaneous coefficient,with the data of the quantity of year-end pigs from 1952-2007.The results show that the result of simultaneous coefficient is more scientific than that of correlation coefficient;the co-movement of hog output fluctuation between Shaanxi and China is up to 0.7636,and the co-movement is becoming higher and higher;Shaanxi’s hog output fluctuation could be taken as an observation point to forecast the trend of hog output fluctuation of the whole nation. |
