Abstract
In the recent two decades, thanks to the great changes from State-Owned Enterprises and planned economy to modern market-oriented economy in China, and the explicitation of the social class, subsistence right(the right to live) has became a more important and urgent need not only to the aspect of common lives and psychological affects of the Chinese individuals ,but also to the practical influence of each social class. Common people's subsistence right being threatened, repeatedly checks the legality of the current constitutionalism in the country;however, when a country's independence and existence are in danger, people's subsistence rights cannot be guaranteed. That is why people's subsistence rights must be based on the subsistence right of the Chinese country. If we want to make the theory of constitutionalism meet the practical needs of constitutionalism at present time ,we'll be urgent for raising up the status of the subsistence right and having researches into it at a proper status fitting the modern society.
Key words: subsistence right, China, constitutionalism, significance.
