包装品在福建省的需求价格弹性分析数据

本行业所有企业经营的包装品多年以来在该省市场广受欢迎，为更好了解各市对包装品的市场需求情况，本行业所有企业对相关包装品需求弹性数据进行采集计算。采集相关包装品在某一时间段在该省的需求数据和价格数据，得到该包装品的需求价格弹性，如果包装品需求量变动的比率大于价格变动的比率，那么包装品需求富有弹性，说明顾客对于包装品价格变化的敏感程度大，弹性越大，需求对价格变化越敏感，本行业所有企业可以适当的降低包装品价格来获得较多的收益。那么包装品需求缺乏弹性，本行业所有企业可以适当的提高包装品价格来获得较多的收益。该项数据对本行业所有企业在该省的市场营销决策有重要意义。1.数据采集：采集相关包装品在某一时间段该省的的需求数据和价格数据，每个省按照市级单位进行整理归纳，得到该包装品的需求量变动数值和价格变化数值。 2.算法规则：对采集得到的数据按照如下公式进行计算：需求弹性系数Ed=-(△Q/Q)÷(△P/P），得到需求弹性系数。式中：Q表示产品的需求量，单位为份；P表示产品的价格，单位为元；△Q表示需求量同比变动值，单位为份；△P表示价格同比变动值，单位为元。取需求弹性系数的绝对值|Ed|作为分析数据时的参考系数。 3.数据分析：根据|Ed|的数值可分析该包装品的需求价格弹性。（1）|Ed|=1（单位需求价格弹性），说明需求量变动幅度与价格变动幅度相同；（2）1<|Ed|（需求富有弹性），说明需求量变动幅度大于价格变动幅度；（3）|Ed|<1（需求缺乏弹性），说明需求量变动幅度小于价格变动幅度。

All packaging products operated by enterprises in this industry have enjoyed widespread popularity in the provincial market for many years. To better understand the municipal-level market demand for packaging products, all enterprises in the industry have collected and calculated demand elasticity data for relevant packaging products. First, collect demand and price data of relevant packaging products in the province over a specific time period to obtain the price elasticity of demand (PED) for the packaging products. If the percentage change in the quantity demanded of packaging products is greater than the percentage change in price, the demand for packaging products is price elastic, indicating that customers are highly sensitive to changes in packaging product prices. The greater the elasticity, the more sensitive demand is to price changes. In this case, all enterprises in the industry can appropriately lower the prices of packaging products to achieve higher revenue. Conversely, if the demand for packaging products is price inelastic, all enterprises in the industry can appropriately increase the prices of packaging products to achieve higher revenue. This dataset is of great significance for the marketing decision-making of all enterprises in this industry within the province.

1. Data Collection: Collect demand and price data of relevant packaging products in the province over a specific time period, then organize and summarize the data at the municipal administrative level within the province to obtain the changes in the quantity demanded and price changes of the packaging products.

2. Algorithmic Rules: Calculate the collected data using the following formula to obtain the demand elasticity coefficient: $E_d = -frac{Delta Q/Q}{Delta P/P}$. Where: $Q$ represents the quantity demanded of the product, with the unit of "unit"; $P$ represents the price of the product, with the unit of "yuan"; $Delta Q$ represents the year-over-year change in quantity demanded, with the unit of "unit"; $Delta P$ represents the year-over-year change in price, with the unit of "yuan". The absolute value of the demand elasticity coefficient $|E_d|$ is taken as the reference coefficient for data analysis.

3. Data Analysis: The price elasticity of demand for the packaging products can be analyzed based on the value of $|E_d|$:
(1) $|E_d|=1$ (Unitary price elasticity of demand): indicating that the percentage change in quantity demanded is equal to the percentage change in price;
(2) $1 < |E_d|$ (Price elastic demand): indicating that the percentage change in quantity demanded is greater than the percentage change in price;
(3) $|E_d| < 1$ (Price inelastic demand): indicating that the percentage change in quantity demanded is less than the percentage change in price.
