(1) The monopoly degree of economic development has increased rapidly, and it has gradually moved from private monopoly and industry monopoly to national monopoly, and further developed to international monopoly. A large number of multinational companies have emerged, and their influence is expanding day by day. Multinational companies are not only numerous, but also have large assets and a wide range of business. Transnational monopoly has formed a new stage of monopoly development. The process of economic regionalization, integration and globalization has obviously accelerated, and the influence of global economic organizations is increasing day by day (among them, the World Trade Organization, the International Monetary Fund and the World Bank are the three most famous world economic organizations), and among these international economic organizations, western developed capitalist countries occupy a dominant position. They actually control these organizations and control the global economy by controlling these international economic organizations.

(2) Great changes have taken place in the mode of economic growth, from attaching importance to the development of tangible capital to the development of virtual capital. After the war, western capitalist countries experienced more than ten years of economic recovery and development. During this period, they generally attached importance to the development of material capital. However, since the 1960s and 1970s, the focus of economic development has gradually shifted from paying attention to physical capital to virtual capital, and the disconnect between them has become increasingly obvious. Especially after the collapse of the Bretton Woods system in the early 1970s, the financial industry and financial derivatives developed rapidly, which led to the serious separation of finance, stock market, foreign exchange market and futures market from physical capital. The gambling and speculative nature of capitalist economy is increasingly obvious and strengthened. The largest amount of capital in the world does not circulate in the production field, but flows at the speed of light in finance and financial derivatives, which inevitably lurks huge crisis risks.

(3) The expansion of the new middle class generally refers to the intellectuals who are in the middle position in the economy. They are between capitalists and workers (usually managers and white-collar workers) in the economy. In the United States today, these people account for about 25% of the total population.

(4) Major changes have taken place in the industrial structure, mainly due to the relative decline in the status of the primary and secondary industries and the rapid increase in the proportion of the tertiary industry. At present, the tertiary industry in developed countries accounts for about 60% of the whole national economy, and there is a further upward trend. Some industries with great development potential mostly belong to the category of tertiary industry, such as communications, finance, insurance, tourism and other industries. For example, from 65438 to 0996, the primary industry accounted for 2% of the national economy, the secondary industry accounted for 25% and the tertiary industry accounted for 73%.
