【Abstract】In this paper, translog gravity is revised and the domestic democratization as political factor is introduced into it from two paths of export and import. Based on the revised model, the paper measures the agricultural trade cost elasticity in 28 kinds between China and BRICS. The result shows all the elasticity is positive, which means reducing trade cost could increase the volume of trade for the BRICS. However, the difference value between export and import cost elasticity is negative, which implies China does not have a comparative advantage in general. As for the product structure, the superior products should be given priority to promote trade liberalization and facilitation. There exists the potential of intra-industry products trade between China and BRICS. China could deepen division of labor and cooperation with BRICS to reduce trade risk and realize diversification in sustainable development.

    [5]. ① In this paper, we set σ to 8 with reference to the Novy (2013), for more details please see note 29 of Novy (2013). [^Back]

    [6]. ② Novy considers that and is respectively the fixed effect of the exporting and importing countries, and can be used as the control variable when estimating the equation: when the exporting country is the country i, assign it to 1; similarly, when the importing country is the country j, assign it to 1; therefore, there is no need to find the Pj or IIi. [^Back]

    [7]. ③ We select the time period after 2000 as the research sample of this paper; one important reason is that the time of proposal of the concept of “BRIC” is 2001; therefore we take the year 2000 as the beginning of time in this paper. [^Back]

    [9]. ⑤ The traditional gravity model takes only the xij as the explanatory variable, so what it reflects is the change of the absolute amount. [^Back]
