哈尔滨市跨境电商出口海外金额分析数据

通过系统录入的方式进行清洗、加工、汇总，汇总跨境销售每个月各区域各行业出口各个国家的出口金额，通过计算各个区域每个月出口金额的方差大小，以用来评价各个区域的出口情况，从而用于评估各区域所有企业的生产和出口策略，本行业所有企业可以通过往年数据了解本行业在该国的淡旺季，以平衡生产和出口数量。步骤1：统计跨境出口各个年度的每个月出口各个国家的出口金额（以人民币万元为单元），并依次用x1,x2...x12表示（一月出口金额=x1，x2...），并汇总计算得到当年的总出口金额=x。步骤2：计算月平均出口金额x̅=总出口金额x/12，结果取小数点后三位。步骤3：根据方差公式，计算方差s2={(x1-x̅)^2+(x2-x̅)^2+(x3-x̅)^2+…+(x12-x̅)^2}/12，结果取小数点后三位。步骤4：当方差s2小于0.5评价该国为出口超平稳型区域。当方差s大于等于0.5并且小于等于1评价该国为出口一般平稳型区域。当方差s2大于1评价该国为出口波动型区域。对于出口超平稳型区域，本行业所有企业无需时时关注该国行情，可每月保持好产品的生产和出口数量；对于出口一般平稳型区域，本行业所有企业需每季度关注该国行情，适应调整产品的生产和出口数量；而对于出口波动型区域，本行业所有企业需每月关注该国行情，了解淡旺季情况变化，大幅度调整产品的生产和出口数量

This dataset is cleaned, processed and aggregated via systematic entry to compile the monthly export amount of each region, industry and destination country for cross-border sales. The variance of the monthly export amount of each region is then calculated to evaluate the export performance of the region, so as to assess the production and export strategies of all enterprises in the region. All enterprises in the industry can use historical data to understand the peak and off-peak seasons of their industry in the target country, so as to balance production and export volume.

The specific steps are as follows:
Step 1: Count the monthly export amount (in units of ten thousand RMB) to each destination country for each year of cross-border exports, denote them as x₁, x₂, ..., x₁₂ respectively (x₁ represents the export amount of January, and so on), and calculate the total annual export amount as x.
Step 2: Calculate the monthly average export amount x̅ = total annual export amount x / 12, retain three decimal places for the result.
Step 3: Calculate the variance s² according to the variance formula: s² = [(x₁ - x̅)² + (x₂ - x̅)² + (x₃ - x̅)² + … + (x₁₂ - x̅)²] / 12, retain three decimal places for the result.
Step 4: Classify the regions based on the calculated variance:
- If the variance s² < 0.5, the destination country is evaluated as an ultra-stable export region;
- If the standard deviation s (where s = √s²) is ≥ 0.5 and ≤ 1, the destination country is evaluated as a generally stable export region;
- If the variance s² > 1, the destination country is evaluated as a volatile export region.

Corresponding operational suggestions for each region:
For ultra-stable export regions, all enterprises in the industry do not need to closely monitor the market conditions of the country, and can maintain consistent product production and export volumes each month;
For generally stable export regions, all enterprises in the industry need to monitor the market conditions of the country every quarter and adjust product production and export volumes appropriately;
For volatile export regions, all enterprises in the industry need to closely monitor the market conditions of the country every month, understand changes in peak and off-peak seasons, and make significant adjustments to product production and export volumes.
