洞头区农贸市场包心菜价格浮动数据

政府或市监单位可以通过监测农贸市场的均价以及均价的正、负浮动值，并分别设定一个合理的正浮动补贴价格与负浮动补贴价格，若市场价格高于正浮动的补贴价格，政府或市监单位可根据差价对生产者进行补贴，从而稳定市场价格（即降价），若市场价格低于负浮动的补贴价格，政府或市监单位可根据差价对生产者进行补贴，从而保障生产者的利益和生产积极性。1、数据采集：从本地服务器中提取农贸市场关于包心菜2022年~2023年当中每日的最高价与最低价：2、处理数据：将每日的最低价与最高价分别进行累加，进而得到A（最低价总和）与B（最高价总和），进一步通过公式（A+B）/2/730得出包心菜的C（均价），进一步提取2022年~2023年中最高价的峰值与最低价的谷值，该峰值与谷值分别作为该数据的最高价与最低价，进一步将(最高价与C（均价）的差的绝对值）/C（均价）*100%，从而得出+浮动值，进一步将(最低价与C（均价）的差的绝对值）/C（均价）*100%，从而得出-浮动值，进一步根据得出的+浮动值与-浮动值确定均价浮动比（-浮动值~+浮动值）。

Government or market supervision authorities can monitor the average price of farmers' markets and the positive and negative fluctuation ranges of the average price, and set a reasonable positive fluctuation subsidy price and negative fluctuation subsidy price respectively. If the market price exceeds the positive fluctuation subsidy price, the government or market supervision authorities can subsidize producers based on the price difference to stabilize market prices (i.e., reduce prices). If the market price is lower than the negative fluctuation subsidy price, the government or market supervision authorities can subsidize producers based on the price difference to protect producers' interests and production enthusiasm.
1. Data Collection: Extract the daily highest and lowest prices of cabbage from local servers at farmers' markets from 2022 to 2023.
2. Data Processing: Sum the daily lowest prices and highest prices separately to obtain A (total lowest price) and B (total highest price). Calculate C (the average price of cabbage) using the formula (A + B) / 2 / 730. Extract the peak value of the highest prices and the trough value of the lowest prices from 2022 to 2023, which are respectively taken as the overall highest and lowest prices of this dataset. Calculate the positive fluctuation value as (|overall highest price - C|) / C * 100%, and the negative fluctuation value as (|overall lowest price - C|) / C * 100%. Finally, determine the average price fluctuation ratio (negative fluctuation value ~ positive fluctuation value) based on the calculated positive and negative fluctuation values.
