How to calculate the growth rate of effective invention patents?

The calculation formula is: the number of invention patents per 10,000 people = the number of invention patents at the end of the year/the total population at the end of the year. 20 1 1 is the first year of the 12th Five-Year Plan. The quantitative index of increasing the number of invention patents per 10,000 population to 3.3 has been included in the Twelfth Five-Year Plan for the first time, which has become an important part of the comprehensive assessment index system for national economic and social development. The number of invention patents per 10,000 population is an international general index, which mainly reflects the independent innovation ability of a country or region. Patents are generally divided into three types: invention patents, utility model patents and design patents. Among the three patents, the invention patent has the highest technical content, the greatest innovation value, the strongest core competitiveness and the longest protection period, reaching 20 years. Invention patents can best reflect the independent innovation ability of a region. It is not only an intangible intellectual property, but also can be transformed into real wealth through industrial production and manufacturing. It is a comprehensive index to measure the quality of scientific research output and the level of market application in a region. It took six years (1 99 1 year) for China to authorize 1 10,000 invention patents, and 12 years (2003), from authorizing110,000 to authorizing 65438. It is reported that by the end of the second quarter of 20 12, the cumulative number of invention patents accepted in China National Intellectual Property Administration reached 3114,000, and by mid-July, the cumulative number of invention patents granted in China reached10,000, including 518,000 domestic invention patents. In recent years, China's invention patent authorization has shown three characteristics: the annual number of invention patents has increased rapidly, the proportion of domestic applicants who have obtained invention patents has been increasing, and the proportion of domestic authorized inventions has increased year by year. By the end of 20 1 1, China had 35 1 10,000 domestic invention patents, which exceeded the number of foreign invention patents in China for the first time. At the same time, the number of invention patents per 10,000 population reached 2.37, which laid a solid foundation for realizing the goal of invention patents per 10,000 population set by the National Twelfth Five-Year Plan. reference data
