瓯海区农贸市场草鱼价格浮动区间的数据

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草鱼2023年一年当中每日的菜品最高价与最低价：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（菜品最低价总和）与B（菜品最高价总和），进一步通过公式（A+B）/2/365得出草鱼的C（均价），进一步提取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年最高价与年最低价，进一步将(年最高价与C（均价）的差的绝对值）/C（均价）*100%，从而得出+浮动值，进一步将(年最低价与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-浮动值确定均价的浮动区间（-浮动值~+浮动值）。

Government or market supervision authorities can monitor the average price of agricultural products at farmers' markets as well as the positive and negative fluctuation ranges of this average price, and set reasonable positive fluctuation subsidy prices and negative fluctuation subsidy prices 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., lower them). If the market price is lower than the negative fluctuation subsidy price, the authorities can subsidize producers based on the price difference to safeguard producers' interests and production enthusiasm.
1. Data Collection: Extract the daily highest and lowest prices of grass carp from the local server for the full year of 2023, sourced from local farmers' markets.
2. Data Processing: First, sum the daily lowest and highest prices separately to obtain A (total sum of the product's lowest prices) and B (total sum of the product's highest prices). Further calculate the average price C of grass carp using the formula (A + B) / 2 / 365. Next, extract the peak value of the daily highest prices and the trough value of the daily lowest prices in 2023, which are taken as the annual highest price and annual lowest price of this dataset respectively. Then calculate the positive fluctuation value via the formula: |annual highest price - C| / C * 100%, and calculate the negative fluctuation value via the formula: |annual lowest price - C| / C * 100%. Finally, determine the fluctuation interval of the average price as (-negative fluctuation value ~ +positive fluctuation value) based on the obtained positive and negative fluctuation values.
