American sugar 1 1 is the American international sugar price, and American sugar 14 is the American local sugar price. Indicators are divided into individual indicators and total indicators according to the scope of the phenomenon; 1 1 is just a code name, such as sugar 1 1. Sugar 14. Sugar 1 1 is the international sugar price in the United States, and sugar 14 is the local sugar price in the United States. The variety of sugar traded in external futures is sugar11.11,which belongs to the international sugar futures contract. The price formed by international sugar futures is FOB ports of 29 sugar-producing countries around the world, which is mainly the "wind vane" of international raw sugar prices and provides settlement prices for international raw sugar trade. The index of sugar 1 1 is also compiled by Wenhua himself, which is calculated by the weighted average of sugar 1 1, reflecting the overall trend of sugar 1 1. The index is divided into individuals according to the different phenomena reflected. Index, or statistical index, is an important statistical method to analyze the quantitative changes of social and economic phenomena. It came into being in the second half of18th century. At that time, due to the continuous inflow of gold and silver mined in the New World of America into Europe, the prices in Europe suddenly rose, which aroused widespread concern in society. In order to measure price changes, economists began to try to compile price indexes.

An index is a relative number representing the dynamics of social and economic phenomena, which can be used to determine the overall dynamics of social and economic phenomena that cannot be directly added and compared. We can analyze the influence degree of various factors in the total change of social and economic phenomena; We can study the role of the changes in the score level and overall structure of each group in the total average index.

1. According to the different nature of the reflected phenomenon, it can be divided into quantitative indicators and quality indicators. Quantitative indicators Quantitative indicators reflect changes in the quantity of production, operation or economic activities, such as commodity sales index; Quality index Quality index is an index that explains the quality change of economic activities, such as product cost index and labor productivity index. According to different calculation forms, it can be divided into comprehensive index and average index. The former refers to the index calculated by comparing two total indicators, and the latter is the deformation of the former.

2. General relative number is the ratio of two related indicators, which can quantitatively reflect the contrast between two related phenomena. There are many kinds of relative numbers, which can be divided into two types according to their manifestations: one is the nominal number, that is, the relative number calculated by comparing two absolute numbers or averages with different properties and connections, which are generally nominal numbers and use more units of measurement. The other is the unknown, which can be expressed by multiples, fractions, coefficients, percentages, thousandths, etc. According to different conditions such as birth rate and death rate. Relative number can be divided into five types according to the nature and function of the indicators compared with each other: dynamic relative number, structural relative number, comparative relative number, intensity relative number and planned completion relative number.
