First is their advisory role in enhancing coordinated socio-economic development and providing important reference points for scientific and democratic decision-making by the CPC Central Committee and the State Council. Mr. Li cited examples. At the First Plenary Session of the First National Committee of CPPCC in 1949, 44 democratic personages, including such celebrities as Guo Moruo, Li Jishen, Shen Junru, Huang Yanpei and Ma Xulun, proposed to telegraph the United Nations immediately protesting the representation of China by the Kuomintang Government. These people are remembered in the People's Republic of China related to the PRC's long struggle to regain its legitimate rights in the United Nations.

During the early years of socialist construction, economist Ma Yinchu proposed the idea of birth control, which later exerted a profound and far-reaching influence on the economic and social development of China. In recent decades, proposals that significantly stood out included one that urged a thorough feasibility study of the Three Gorges Project before its implementation and one that called for development of the recycling economy. There were also many suggestions that were closely related to the well-being of the people, such as nullification of the agricultural tax, acceleration of the construction of a social security system, enforcement of food safety supervision, and reform of the housing system. They caught the central government's attention and speeded up finding solutions to these relevant problems.

At the 1998 CPPCC Session, the Central Committee of China Democratic National Construction Association (CDNCA) proposed that China should institutionalize risk investment. The State Planning Commission, Economic and Trade Commission, Ministry of Science and Technology, People's Bank of China, and State Securities Commission held several forums with the CDNCA Central Committee, discussing actual implementation. Now the risk investment sector is developing rapidly in China.

Second, CPPCC proposals have helped enhance the solidarity of the united front by calling on the wisdom and resources of various sectors. Involvement through filing proposals has the advantage of flexibility, broad participation and marked effectiveness. Both individual and institutional members can present public opinions and suggestions through their proposals to relevant government departments. And in fact, their proposals reflect the mind and needs of various sectors, ethnic groups, social echelons and people from all walks of life; they are the result of collective wisdom and serve as a huge intelligence bank.

In 2009, the subcommittee received 1,100 proposals on the topics of grassroots democracy, solidarity of various ethnic groups, rapprochement among different religions, the implementation of the "one country, two systems" and overseas Chinese affairs policies, cross-Straits exchanges, and clean government. They have helped the CPC and government departments with their public relations and contributed to social stability. One of these proposals focused on the salt tide that had hit Macao and the Pearl River Delta and threatened the potable water safety. The Ministry of Water Resources has followed up the issue closely and guaranteed safe water supply to the affected areas.
