杭州地区珠宝首饰综合拍卖分析数据

通过对中科检测技术研究所鉴定评估过的杭州市法拍数据进行跟进，根据实际拍卖的数据情况进行分析，给出评分结论。研究所根据数据分析数据调整评估策略与专家意见。同时数据可以为法拍行业提供数据支持及参考。通过对中科检测技术研究所鉴定评估过的杭州市法拍数据进行跟进及评估价（元）、拍卖价格（元）、出价次数等数据进行分析，进行拍卖价格评分：x=（最终价格-评估价格）/评估价格*100,x<0则评分为0， 0<=x<10则评分为 1, 10<=x<30则评分为2,30<=x则评分为3 拍卖次数评分：出价次数=0则评分为0，0<出价次数<=3则评分为1 ,3<出价次数<=8则评分为2,8<出价次数则评分为3 拍卖参与评分:y=围观人数/100+报名人数，y=0则评分为0，0<y<5则评分为 1,5<=y<10则评分为 2,10<=y则评分为 3 综合评分（z）等于拍卖价格评分+卖次数评分+拍卖参与评分 拍品分级：z=0则分级为 D,0<z<4则分级为 C,4<=z<7则分级为 B,7<=z则分级为 A。

Follow-up analysis is conducted on Hangzhou judicial auction data that has been identified and evaluated by the Zhongke Testing Technology Research Institute, and scoring conclusions are generated based on actual auction data. The institute adjusts its evaluation strategies and expert opinions based on the data analysis results. Additionally, this dataset can provide data support and reference for the judicial auction industry.

Specifically, by analyzing the Hangzhou judicial auction data (including evaluated price (CNY), final auction price (CNY), number of bids, etc.) identified and evaluated by the said institute, the following scoring rules are formulated:
1. Auction Price Score: Calculate $x = frac{ ext{Final Auction Price} - ext{Evaluated Price}}{ ext{Evaluated Price}} imes 100$. The scoring criteria are: 0 points if $x < 0$; 1 point if $0 leq x < 10$; 2 points if $10 leq x < 30$; 3 points if $x geq 30$.
2. Auction Frequency Score: 0 points if the number of bids equals 0; 1 point if $0 < ext{number of bids} leq 3$; 2 points if $3 < ext{number of bids} leq 8$; 3 points if $ ext{number of bids} > 8$.
3. Auction Participation Score: Calculate $y = frac{ ext{Number of Onlookers}}{100} + ext{Number of Registered Participants}$. The scoring criteria are: 0 points if $y = 0$; 1 point if $0 < y < 5$; 2 points if $5 leq y < 10$; 3 points if $y geq 10$.

The comprehensive score ($z$) is equal to the sum of the Auction Price Score, Auction Frequency Score and Auction Participation Score. The lot grading standards are: Grade D if $z = 0$; Grade C if $0 < z < 4$; Grade B if $4 leq z < 7$; Grade A if $z geq 7$.
