Vitamin C，also known as ascorbic acid，is a widely used health care product，medicine，food additive and cosmetic nutrient. Since the reform and opening-up，our country’s Vitamin C industry has been on a rapid development path. Its production capacity and output have been increasing year by year，and the export volume has increased year after year. After just about 40 years，China has become the world’s largest producer and exporter of Vitamin C. Due to its lower production costs，higher profits，and selling well all over the world，market competition has been fierce. Our country’s Vitamin C already has an absolute competitive advantage in the global market：it has independent intellectual property rights，low production costs，high industrial concentration，advanced production technology，large-scale equipment，strong competitiveness，high market share，and the right to speak in the international market. According to the analysis，our country’s Vitamin C market will continue fierce competition for a period of time，and the price war will begin at any time. At present，all major Vitamin C producing enterprises in our country are large companies with great strength. These companies will not be easily defeated by the price war，nor will they withdraw from the Vitamin C industry.
