It makes China＇s agriculture modernization under the background of internationalization. Therefore, the integration of China＇s agricultural modernization and internationalization becomes an inevitable choice in developing China＇s modem agriculture. This paper takes the practice of agricultural modernization and internationalization in the area of eastern Shandong province as a basis and uses Panel Data model to analyze the interact relationship between agricultural modernization and internationalization quantificationally with the data of the seven cities in the area of eastern Shandong. The result indicates that agricultural modernization and internationalization have the relationship of interact development.展开更多

The proposed methodology reduces the curve regression problem to ordinary(i.e., scalar) additive regression problems of the singular components of the predictor process and response process. Consistency of estimators for the nonparametric function and prediction are proved, respectively. A simulation study is conducted to investigate the finite sample performances of the proposed estimators.展开更多
