公共选择理论给我们这样一个启示 :为了防止权力滥用 ,必须进行宪制选择 ;宪制选择的方向是有限政府。中国市场经济的实践表明 ,从计划经济到市场经济 ,从全能政府到有限政府 ,是市场经济和政府发展的必然规律。产权保护是市场经济发展对现代宪政和有限政府提出的必然要求。中国修宪 ,对公民合法的私有财产进行保护 ,合乎从市场经济到有限政府、法治政府、现代宪政的理论前提和必然逻辑 Public choice theory gives us such a revelation: in order to prevent abuse of power, must make a constitutional choice; the direction of constitutional choice is a limited government. The practice of China’s market economy shows that from the planned economy to the market economy and from the all-powerful government to the limited government, it is the inevitable law of market economy and government development. Property rights protection is a necessary requirement of the development of market economy to the modern constitutional government and the limited government. China’s constitutional amendment and the protection of the legitimate private property of its citizens are in line with the theoretical premises and inevitable logic from the market economy to the limited government, the government under the rule of law and the modern constitutional government
