The invention provides a reinforcing bar for reinforced concrete and medium and high strength stirrup, which has the advantages of 600 to 1,200N/mm<2> yield strength, high specific elongation, good flexural property and good anchoring property and weldability, and a method for manufacturing the same, wherein according to the weight percentage, a hot finished rod containing 0.15 to 0.30 percent of C, 0.5 to 1.5 percent of Mn and less than or equal to 2.0 percent of Si, and also containing one or two of Nb, Ti, V and B alloy elements is used as raw materials, and is subjected to draw forming by a die or a roller die, or directly subjected to heat treatment process without drawing to obtain the reinforcing bar. The range of the heat treatment process is as follows: the quenching temperature is between 850 and 1,100 DEG C, and the drawing temperature is between 350 and 550 DEG C. The surface of the reinforcing bar is circular, belt rib or spiral rib shaped and spiral groove shaped.
