The catering industry and the clothing industry are both processing industries and are secondary industries. These industries are linked to the price of raw materials. If an economic crisis occurs, these industries will be the first to go bankrupt.
The primary industry is manufacturing, such as farmers and fishermen. The tertiary industry refers to service industries, such as travel companies, game agencies, etc.
These industries will also be affected when the economic crisis breaks out, but not as much as the secondary industry. In the past 10 years, the fourth industry, an emerging industry, has emerged - mainly referring to industries engaged in high technology or technology research and development. For example, Microsoft and Nintendo mentioned on the first floor, as well as the pharmaceutical industry, and even drug refining.
Because their costs are generally very low, their products mainly sell technology patents or high-content technical essence. Analyzing it from another perspective, if you are engaged in a monopoly industry, your risk will always be minimal regardless of whether there is an economic crisis or not. Because you have a grasp of the supply and demand relationship in the entire market, the power to determine the price is in your hands.

Characteristics and trends of modern energy production and consumption:
The amount of energy production and consumption is increasing and growing rapidly. Both the world's total energy consumption and per capita consumption have been growing continuously. For example, between 1850 and 1950, energy consumption increased from 100 million tons to 2.5 billion tons. In 1980, it increased 2.8 times compared with 1950, and in 1988 it exceeded 10 billion tons (standard fuel).
Per capita consumption increased from 115 kilograms to 1,000 kilograms from 1850 to 1950. After entering the 1980s, it exceeded 2000 kilograms. It is predicted that the world's total energy supply in 2000 will be 14.66 to 18.17 billion tons (standard fuel). The reasons for the rapid growth of world energy production and consumption can be summarized as follows:
(1) The rapid economic growth of various countries in the world has increased energy demand;
(2) The increase in population It is also an important factor affecting the increase in world energy demand;
(3) After the Second World War, the industrial structure of developed countries accelerated the transformation to heavy and chemical industries, especially the development of energy-intensive industries, which increased energy consumption. The volume shows an unprecedented growth rate.
Heavy industries in many developing countries have also developed greatly, which has increased energy consumption. In the future, with the development of science and technology, the industrial structure of many industrialized developed countries will develop in the direction of technology-intensive and economic service-oriented, and the natural growth rate of the world's population will show a downward trend, etc.
