“…There are several ways of using the RCA indexes in measuring trade performance, including comparing the calculated value with the neutral point, comparing given sectors by using the calculated value, and comparing the calculated value at the national or regional level [ 14 , 43 ]. Given that agricultural trade is an important part of overall economic activity, continues to play a major role in domestic agricultural production and employment and also plays a fundamentally important role in global food security, some existing studies measured the comparative advantage of agricultural trade at national and regional levels by utilizing the RCA indexes, such as Serbia [ 40 ], Hungary [ 44 ], Russia [ 45 ], China [ 46 ], Pakistan [ 47 ], Indonesia [ 48 ], Myanmar [ 14 ], India [ 49 ], Brazil [ 50 ], Canada [ 51 ], and Ghana [ 52 ]. Despite the utilization of the RCA indexes analysis over the past decades, the existing research on the comparative advantage of countries along the B&R and China mainly focuses on the manufacturing industry, and there were relatively few studies on the comparative advantage of agricultural trade in the two sides from a dynamic perspective [ 35 , 53 , 54 , 55 ].…”
