USB拓展器在安徽省的需求价格弹性分析数据

为更好了解安徽省各市对USB拓展器的市场需求情况，采集安徽省各市的相关USB拓展器需求弹性数据进行计算。如果USB拓展器需求量变动的比率大于价格变动的比率，那么USB拓展器需求富有弹性，说明顾客对于USB拓展器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在该市适当降低USB拓展器价格来获得较多的收益。如果USB拓展器需求缺乏弹性，本行业所有企业可以在该市适当的提高USB拓展器价格来获得较多的收益。该项数据对本行业所有企业在安徽省的市场营销决策有重要意义。1.数据采集：采集相关USB拓展器在安徽省每个月的需求数据和价格数据，按照市级进行整理归纳，得到该USB拓展器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USB拓展器的需求价格弹性。（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。

To better understand the market demand for USB expanders across cities in Anhui Province, this dataset collects and computes demand elasticity data for USB expanders in each city of Anhui Province. If the ratio of the change in quantity demanded of USB expanders exceeds the ratio of the change in their price, the demand for USB expanders is deemed price-elastic, meaning that customers are highly sensitive to price fluctuations of such products. The larger the elasticity value, the more sensitive demand is to price changes. Under this scenario, all enterprises in the industry can appropriately lower the price of USB expanders in the corresponding city to generate higher revenue. Conversely, if the demand for USB expanders is price-inelastic, all enterprises in the industry can appropriately raise the price of USB expanders in the corresponding city to gain higher revenue. This dataset holds significant importance for the marketing decision-making of all enterprises in the relevant industry operating within Anhui Province.

1. Data Collection: Collect monthly demand and price data of relevant USB expanders, then organize and aggregate the data at the municipal level to derive the change values of the quantity demanded and price changes of USB expanders.
2. Algorithm Rules: Calculate the demand elasticity coefficient using the following formula: $E_d = - frac{Delta Q / Q}{Delta P / P}$, where $Q$ denotes the quantity demanded of the product, with the unit of unit; $P$ denotes the price of the product, with the unit of yuan; $Delta Q$ represents the year-on-year change in quantity demanded, with the unit of unit; $Delta P$ represents the year-on-year change in product price, with the unit of yuan. Take the absolute value $|E_d|$ of the demand elasticity coefficient as the reference coefficient for data analysis.
3. Data Analysis: Analyze the price elasticity of demand for USB expanders based on the value of $|E_d|$:
(1) $|E_d| = 1$ (unitary price elasticity of demand): indicating that the magnitude of change in quantity demanded is identical to that of price change;
(2) $1 < |E_d|$ (price-elastic demand): indicating that the magnitude of change in quantity demanded is greater than that of price change;
(3) $|E_d| < 1$ (price-inelastic demand): indicating that the magnitude of change in quantity demanded is smaller than that of price change.
