乐清市农贸市场猪全精肉价格浮动区间数据

市场开发服务中心、政府或市监单位可以通过监测农贸市场猪全精肉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，若猪全精肉市场价格高于正浮动的补贴价格，市场开发服务中心、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），若猪全精肉市场价格低于负浮动的补贴价格，市场开发服务中心、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各年乐清市农贸市场关于猪全精肉一年当中每日的菜品最高价与最低价：2、处理数据：将当年每日的最低价与最高价分别进行累加，进而得到当年猪全精肉的最低价总和（A）与最高价总和（B），进一步通过公式（A+B）/2/365得出当年的猪全精肉均价（C），再进一步从本地服务器中提取当年猪全精肉的最高价（D）与最低价（E），根据+浮动值=（D-C）/C*100%以及-浮动值=（E-C）/C*100%公式，计算出+浮动值与-浮动值的大小，从而根据得出的+浮动值与-浮动值确定均价的浮动区间（-浮动值~+浮动值）。

Market development service centers, governments or market supervision authorities can monitor the average price of whole lean pork in agricultural fairs, along with its positive and negative fluctuation values, and set reasonable positive and negative fluctuation subsidy prices respectively. If the market price of whole lean pork exceeds the positive fluctuation subsidy price, such authorities may subsidize producers based on the price gap to stabilize market prices (i.e., lower them). If the market price falls below the negative fluctuation subsidy price, they can subsidize producers based on the price difference to protect producers' interests and their production enthusiasm.
1. Data Collection: Extract the daily highest and lowest prices of whole lean pork from the local server for each year in Yueqing City's agricultural fairs.
2. Data Processing: First, sum all daily lowest prices and highest prices of the target year separately to get the total lowest price (A) and total highest price (B) of whole lean pork for that year. Then calculate the annual average price (C) of whole lean pork using the formula (A+B)/2/365. Next, retrieve the annual highest price (D) and lowest price (E) of whole lean pork from the local server once more. Compute the positive and negative fluctuation values via the formulas: Positive fluctuation value = (D-C)/C * 100%, Negative fluctuation value = (E-C)/C * 100%. Finally, determine the price fluctuation interval of the average price as (-negative fluctuation value ~ positive fluctuation value) based on the calculated fluctuation values.
