To implement the concept will require restricting vested interest groups and effective law enforcement, researchers and legislators said.
"Economic growth over the past three decades has been achieved at the cost of an excessive consumption of energy and an unequal distribution of income," Liu said.
The Gini coefficient is a means of gauging disparities in income and wealth. According to a report by the World Bank, the Gini coefficient for China surged to 0.47 in 2009, exceeding the concept's warning line of 0.4. Thirty years ago, the figure was 0.21 - 0.27.
"Vested interest groups have become the biggest obstacle to social reform. The problem of disparities in income, if left unresolved, will lead to social disorder," Liu warned.
Along with social fairness, Liu said issues likely to be addressed at the session also include supervising the exercise of power and making government more transparent.
According to Liu, people's involvement in these areas could be achieved through better enforcement of their rights to expression and speech, as stated in the Constitution.
As the country braces itself for achieving the goal of creating a socialist legal system with Chinese characteristics, national legislators said the country's legal system remains challenged by abuses of power.
"To improve the legal system, the country needs to focus on law enforcement," Chen Sixi, a member of the National People's Congress Standing Committee, told China Daily.
"Creating the laws to address the problems in the social sector should be advanced as quickly as possible to help tackle the critical problems the country faces," he said.
