revenue for the state, resulting in a state-sector led recovery during the 2009 financial crises while accounting for most of China's economic growth. The Chinese economic model is widely cited as a contemporary form of state capitalism, the major difference between Western capitalism and the Chinese model being the degree of state-ownership of shares in publicly listed corporations. The Socialist Republic of Vietnam has adopted a similar model after the Doi Moi economic renovation but slightly differs from the Chinese model in that the Vietnamese government retains firm control over the state sector and strategic industries, but allows for private-sector activity in commodity production. Politics While major socialist political movements include anarchism, communism, the labour movement, Marxism, social democracy, and syndicalism, independent socialist theorists, utopian socialist authors, and academic supporters of socialism may not be represented in these movements. Some political groups have called themselves socialist while holding views that some consider antithetical to socialism. Socialist has been used by the political right as an epithet, including against individuals who do not consider themselves to be socialists and against policies that are not considered socialist by their proponents. While there are many variations of socialism, and there is no single definition encapsulating all of socialism, there have been common elements identified by scholars. In his Dictionary of Socialism (1924), Angelo S. Rappoport analysed forty definitions of socialism to conclude that common elements of socialism include general criticism of the social effects of private ownership and control of capital—as being the cause of poverty, low wages, unemployment, economic and social inequality and a lack of economic security; a general view that the solution to these problems is a form of collective control over the means of production, distribution and exchange (the degree and means of control vary amongst socialist movements); an agreement that the outcome of this collective control should be a society based upon social justice, including social equality, economic protection of people and should provide a more satisfying life for most people. In The Concepts of Socialism (1975), Bhikhu Parekh identifies four core principles of socialism and particularly socialist society, namely sociality, social responsibility, cooperation and planning. In his study Ideologies and Political Theory (1996), Michael Freeden states that all socialists share five themes: the first is that socialism posits that society is more than a mere collection of individuals; second, that it considers human welfare a desirable objective;
