本文运用相关性、协整性、回归分析、异方差检验和因果关系等方法全方位检验了中国园艺产品出口价格与世界进口价格之间的互动关系,并应用VEC模型对它们的波动性进行了分析。结论表明,中国园艺产品市场在国际上处于从属地位,与国际市场一体化程度不高。
In this paper, we use the methods of correlation, cointegration, regression analysis, heteroskedasticity test and causal relationship to test the interaction between export prices of China’s horticultural products and world import prices in all aspects and apply VEC model to their volatility analysis. The conclusion shows that the horticultural product market in China is in a subordinate position internationally and is not highly integrated with the international market.
