瓯海区农贸市场空心菜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空心菜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得出空心菜的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 may monitor the average price of local agricultural produce markets and its positive and negative floating values, and set reasonable positive floating subsidy prices and negative floating subsidy prices respectively. If the market price exceeds the positive floating 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 floating subsidy price, the authorities can subsidize producers based on the price difference, thereby protecting producers' interests and production enthusiasm. 1. Data Collection: Extract the daily highest and lowest prices of water spinach (Ipomoea aquatica) from the local server over the entire year of 2023. 2. Data Processing: First, sum the daily lowest prices and highest prices separately to obtain A (total sum of the vegetable's lowest prices) and B (total sum of the vegetable's highest prices). Further calculate C (the average price of water spinach) using the formula (A + B) / 2 / 365. Next, extract the annual peak highest price and trough lowest price recorded in 2023, which will serve as the annual highest and lowest prices of this dataset respectively. Then calculate the positive floating value as [(|annual highest price - C|) / C] × 100%, and the negative floating value as [(|annual lowest price - C|) / C] × 100%. Finally, determine the floating interval of the market price relative to the average price as (-floating value% ~ +floating value%) based on the obtained positive and negative floating values.
