Results of the article are as follows:A- The positive industrial demand shocks have been effective on the production of some of the large industrial plants but they dont affect some of others.B- The negative industrial demand shocks have not had a meaningful effect on the production of large industrial plants.C- Industrial demand shocks have not had asymmetrical effects on the production of all industries. They have had asymmetrical effects on industries with code numbers, 16, 17, 18, 19, 20, 21, 22, 24, 28, 30, 33 and 36, but they havent asymmetrical effects on others industrie's production.D- Intensity of the affects of industrial demand shocks is not the same in the production of different industries.
