National environment plays a significant role in ensuring “international success” and “competitiveness” of an industry. Flexibility is a paradigm with a dynamic interaction capacity and is relevant in competitiveness analysis studies. This paper is an attempt to assess the shrimp industries of India and Thailand, with the help of the two theories of flexibility and competitiveness. The results provide evidence to the tenets of competitiveness held forth by Michael Porter - the scale of success of each of the industries is dependent on its respective national environments. A flexible national environment puts Thailand at an advantageous position than India in the global shrimp export market. The study also reveals an interesting trend through Compounded Annual Growth Rate calculated for a period. In this count, India displays a competitive position as compared to Thailand.
