"Productivity refers to the ratio of the quantity of products or services produced per unit time to the resources, manpower, capital and other production factors used. Productivity is one of the important indicators to measure the economic efficiency of an enterprise or a country.

Productivity is usually expressed by the following formula: Productivity = Production Quantity ÷ Factors of Production

For example, a factory produces 100 products in one hour, using 10 workers, 2 machines and 1000 yuan of raw materials at the same time. Then the production rate of this factory is:

Productivity = 100 ÷ (10 + 2 + 1000)

Productivity = 0.086

Therefore, this factory can produce 0.086 products for every 1 worker, 0.2 machines, and 100 yuan of raw materials. The higher the productivity, the higher the utilization efficiency of unit resources, and the better the economic benefits of the enterprise or the country.

Improve productivity can be achieved by optimizing production process, improving production technology and improving management methods. For example, enterprises can adopt advanced production technology and equipment, strengthen employee training and management, and improve product quality and market competitiveness to improve productivity. The country can also increase the country's productivity by improving the level of education, promoting technological innovation, and strengthening infrastructure construction, thereby promoting economic development and social progress.

In short, productivity is an important indicator to measure the economic efficiency of enterprises and countries, and it can reflect resource utilization efficiency and economic growth rate. Improving productivity is one of the key factors for enterprises and countries to achieve sustainable development. "
