I AM INDIAN NATIONAL VISITING CHINA FOR BUSINESS TRIP CAN I GO TO HONG KONG -MACAU

Of course you can go there. Hong Kong is 14-day entry-free for Indian passport holders and Macau 30 days. So you can go there without the enry permit if you won't stay long. Notice that if you visa for mainland China is single-entry typle, you can't reenter mainland after visiting Hong Kong and Macau.
