大白菜采购价格弹性系数分析数据

采购价格弹性系数是指市场商品采购量对于价格变动作出反应的敏感程度。通常用采购量变动的幅度对价格变动幅度的比值，即采购价格弹性系数来表示。农产品采购价格弹性系数是分析农产品的市场采购需求量对其价格变动反应的灵敏度。通过对大白菜采购价格弹性系数进行分析，可以为：
(1)政府运用支持价格、或限制价格之类经济政策对市场进行干预提供数据支持。
(2)利用市场本身的调节作用机制进行价格调节。
(3)构建有效的信息传导机制，降低菜农盲目生产种植。
(4)组建农产品共富链，加强农产品市场信息服务体系建设。健全市场信息进乡村、进农户的服务网络，及时为农民提供农产品产销、市场供求、价格盈亏等信息，指导生产有序进行。1、数据采集自企业内部，对数据进行清洗，去除异常值、消除重复数据，确保数据的准确性。
2、算法公式：
|Es| =（（Q2-Q1）/（（Q2+Q1）/2））/（（P2-P1）/（（P2+P1）/2 ））
|Es|为采购价格弹性系数，P1为上一期采购价格 (元/Kg）；P2为本期采购价格P2（元/kg)；Q1为上一期采购数量（Kg)；Q2 为本期采购数量（Kg)
（1）富有弹性：|Es| >1，表明采购量变动大于价格变动，意味着需要调整生产规模，以应对价格变化。
（2）缺乏弹性：|Es| <1，即采购量变动小于价格变动，说明价格变动对数量影响较小。
（3）完全弹性：|Es| =∞，表示价格的微小变动会引起采购量的无穷大变动，
（4）单位弹性：|Es| =1，此时采购量变动与价格变动相等
（5）完全无弹性：|Es| =0，采购量对价格变动毫无反应，
3、|Es|反映了采购量变动对于价格变动的反应程度，即价格上升或下降时，采购量的变化情况。

The procurement price elasticity coefficient refers to the sensitivity of market commodity procurement volume to price changes. It is typically expressed as the ratio of the percentage change in procurement volume to the percentage change in price, which is the procurement price elasticity coefficient. The agricultural product procurement price elasticity coefficient measures the sensitivity of the market procurement demand of agricultural products to their own price changes.

Analyzing the procurement price elasticity coefficient of Chinese cabbage can provide support for the following aspects:
(1) Providing data support for the government to intervene in the market via economic policies such as support prices or price ceilings.
(2) Adjusting prices by leveraging the market's own regulatory mechanism.
(3) Constructing an effective information transmission mechanism to reduce blind production and planting among vegetable farmers.
(4) Establishing an agricultural product shared prosperity chain, strengthening the construction of the agricultural product market information service system, improving the service network for market information reaching villages and farmers, timely providing farmers with information on agricultural product production and sales, market supply and demand, price profit and loss, and guiding the orderly conduct of agricultural production.

1. Data was collected from within the enterprise, and data cleaning was performed to remove outliers and duplicate data to ensure data accuracy.
2. Algorithmic formula:
|E_s| = [(Q2 - Q1) / ((Q2 + Q1)/2)] / [(P2 - P1) / ((P2 + P1)/2)]
Where |E_s| is the procurement price elasticity coefficient, P1 is the procurement price of the previous period (yuan/kg); P2 is the procurement price of the current period (yuan/kg); Q1 is the procurement quantity of the previous period (kg); Q2 is the procurement quantity of the current period (kg).
(1) Elastic demand: |E_s| > 1, indicating that the change in procurement volume is greater than the change in price, meaning the production scale needs to be adjusted to respond to price changes.
(2) Inelastic demand: |E_s| < 1, that is, the change in procurement volume is smaller than the change in price, indicating that price changes have a relatively small impact on quantity.
(3) Perfectly elastic: |E_s| = ∞, meaning a slight change in price will cause an infinitely large change in procurement volume.
(4) Unitary elasticity: |E_s| = 1, at which point the change in procurement volume is equal to the change in price.
(5) Perfectly inelastic: |E_s| = 0, where the procurement volume has no response to price changes.

3. |E_s| reflects the degree of response of procurement volume changes to price changes, i.e., the changes in procurement volume when prices rise or fall.
