for IT sector there is no need to worry.they can sustain this for our country growth.only textiles and garments industries are unable to compite much when the rupee appriciate.these sectors are unable to quote lesser than that of china,pakisthan,srilanka and bangladesh where they quote less because of free trade (low duty) government help,modern industrial process and chief labour. now indian govt should think about the huge labour involved in these field and help these sector by means of reduction of duties,giving funds directly to the labour funds, help factories for there mordernisation,make exports eassy.....etc.
To me there is anather way to sustain (I AM NOT A COMMERCE STUDENT) .Bypassing dollar we can quote maximum in euro and other appriciated currencies against dollar which will give less compitition for these sector. anyway the countries export is bound to face the compition from less developing countries, hence nedd to modernise time to time to stay alive in each sector.
