零售商以及在幕后提供支持的公司,可以收集您的位置、搜索内容、购买记录和线上行为等信息。联邦贸易委员会表示,定价系统可以利用个人数据,估算每位消费者愿意支付多少钱。如今,这一问题正在华盛顿引起广泛关注。2026年8月19日,联邦贸易委员会发布了一份针对个性化定价的拟议执法政策声明。
Retailers and the companies working behind the scenes can collect information about where you are, what you search for, what you buy and how you behave online. The FTC says pricing systems can use personal data to estimate how much an individual consumer may be willing to spend. That concern is now getting serious attention in Washington. On Aug. 19, 2026, the Federal Trade Commission published a proposed enforcement policy statement aimed at personalized pricing.
联邦贸易委员会表示,无法在所有情况下禁止这种做法,但如果没有明确告知消费者个人数据如何影响其看到的价格,相关公司可能违反联邦消费者保护法。那么,企业收集的关于你的信息,是否真的会改变你所看到的商品价格、折扣甚至商品本身?研究发现了什么?在下次网上购物之前,你可以做些什么?
The FTC says it cannot ban the practice in every situation, but companies that fail to clearly tell consumers how personal data affects the prices they see could violate federal consumer protection law. So, could the information companies collect about you actually change the price, discount or product you see? Here's what the research shows and what you can do before your next online purchase.

马里兰州计划禁止食品杂货店采用“监控定价”(即根据消费者行为动态调整价格的策略)你可能已经遇到过这种动态定价机制:价格会根据供应情况、市场需求、库存状况、时间或地理位置等因素实时变化。例如,当很多人同时需要租车时,共享出行平台的费用可能会上涨;机票和酒店房间的价格也会随着供需关系的变化而波动。不过,这并不意味着每个消费者看到的价格都完全相同——因为购买时间、地理位置以及其他市场因素会迅速变化。
MARYLAND MOVES TO BAN SURVEILLANCE PRICING IN GROCERY STORES You've probably encountered dynamic pricing already. Dynamic pricing adjusts prices based on broader conditions such as supply, demand, available inventory, time or location. Rideshare fares may rise when lots of people need cars at once. Airline tickets and hotel rooms can also change as availability and demand shift. That does not mean every shopper will always see the exact same dynamic price. Timing, location and other market conditions can change quickly.
另一种更复杂的定价方式是“个性化定价”:商家会利用消费者的个人信息(如浏览习惯、购买历史等)来定制价格或优惠内容。这意味着,即使两个人在搜索同一件商品,也可能因为各自不同的个人信息而收到不同的价格或优惠信息。
Personalized pricing is different because information about a particular consumer helps determine the price or offer that person receives. That means two people looking for the same product could potentially receive different offers because of information connected to them.
此外,还有一种被称为“价格引导”(price steering)的营销手段:商家可能会保持商品的实际价格不变,但调整商品在页面上的显示顺序。美国联邦贸易委员会(FTC)的研究发现,某些定价工具会利用消费者的数据来优先展示某些商品(甚至可能是价格较高的商品)。虽然消费者普遍认为价格会因供需关系而变化,但令人意外的是,价格有时也会受到消费者的浏览习惯、购买历史等个人信息的直接影响。
There's also price steering. A retailer may leave the actual prices alone while changing the order of the products shown to you. FTC research found that pricing tools can use consumer data to give certain products more prominent placement, including potentially showing higher-priced products first. The FTC says consumers generally expect prices to change because of supply and demand. What can come as a surprise is a price influenced by someone's browsing habits, buying history or other personal information.
FTC的进一步研究发现,第三方定价服务提供商在帮助商家制定价格策略时,能够获取极其详细的消费者信息。这些信息可能包括:美国联邦贸易委员会(FTC)发现,其审查的定价中介机构与至少250家客户合作,这些客户销售的商品和服务涵盖食品杂货、服装等。FTC的研究还发现,企业可以将第一方信息与外部来源的数据结合起来。
FTC research into surveillance pricing found that third-party pricing companies can use surprisingly detailed information when helping retailers tailor prices, promotions or product rankings. That information can include: The FTC found that the pricing intermediaries it examined worked with at least 250 clients selling goods and services ranging from groceries to clothing. The FTC's research also found that companies can combine first-party information with data from outside sources.
这些来源可能包括会员积分计划、预订系统、电子商务平台和数据经纪商。但这并不意味着上述每一家客户都会收取个性化价格。研究确实表明,现有技术能够整合详细的消费者信息,并利用这些信息影响价格、折扣以及消费者看到的商品。
Those sources can include loyalty programs, reservation systems, ecommerce platforms and data brokers That does not show that every one of those clients charges individualized prices. It does show that technology exists to combine detailed consumer information and use it to influence prices, discounts and which products shoppers see.
一项较新的调查使优步的案例更贴近当下。2026年6月,《消费者报告》公布了一项历时数月、对优步和 Lyft 定价进行研究的调查结果。该调查招募了174名志愿者,让他们查询了美国各地40多条路线。对于分析中的30条虚拟路线,《消费者报告》发现,最低价格组与最高价格组之间的价格差异中位数为42.4%。
A newer investigation brings the Uber example much closer to today. In June 2026, Consumer Reports published results from a months-long study of Uber and Lyft pricing The investigation used 174 volunteers who checked more than 40 routes across the U.S. For the 30 virtual routes in its analysis, Consumer Reports found a median gap of 42.4% between the lowest and highest price groups.
在一些路线上,相隔几分钟查询同一行程的人会收到多个不同价格。《消费者报告》设计这项研究时,让志愿者大致在同一时间查询路线,以减少基于时间的定价造成的影响。然而,该调查无法控制优步和 Lyft 定价系统中的所有因素,包括司机供给、预计到达时间、交通状况、路线差异和网络延迟。
On some routes, people checking the same trip within minutes of one another received several different prices. Consumer Reports designed the study to reduce the effects of time-based pricing by having volunteers check routes at roughly the same time. However, the investigation could not control for every factor inside Uber's and Lyft's pricing systems, including driver supply, estimated arrival times, traffic, routing differences and network delays.
优步和 Lyft 对《消费者报告》的结论提出异议。两家公司均表示,不会利用个人数据对基础票价进行个性化定价,也不会采用行为定价或监控式定价。因此,这项研究表明,对于在大致相同时间查询的相似行程,乘客可能收到明显不同的价格。但这并不能证明这些价格差异是由个人数据造成的。互联网服务商、网站和广告商能看到什么网络杂货服务又提供了一个令人大开眼界的例子。
Uber and Lyft disputed Consumer Reports' conclusions. Both companies said they do not use personal data to personalize base fares and do not engage in behavioral or surveillance pricing. So, the study shows that riders can receive significantly different prices for similar trips checked around the same time. It does not prove those price differences were caused by personal data. WHAT YOUR INTERNET PROVIDER, WEBSITES AND ADVERTISERS SEE Online groceries have produced another eye-opening example.
2025年12月,《消费者报告》、Groundwork Collaborative和More Perfect Union报告称,他们测试的Instacart食品杂货商品中,近四分之三会向不同购物者提供不同价格。此次调查涉及美国四座城市的437名购物者。
In December 2025, Consumer Reports, Groundwork Collaborative and More Perfect Union reported that nearly three-quarters of the grocery items they tested on Instacart were offered at different prices to different shoppers. The investigation involved 437 shoppers across four U.S. cities.
部分商品的最低价与最高价相差高达23%。研究人员还发现,相同购物篮的总价平均相差约7%。按照Instacart公布的一家四口之家食品杂货支出数据估算 Such a difference over a year could amount to roughly $1,200. Instacart strongly disputed that annual extrapolation and said the limited tests should not be treated as though a household would continually pay higher prices throughout an entire year.
Some items showed differences of as much as 23% between the lowest and highest prices. Researchers also found that totals for identical baskets varied by an average of about 7%. Using an Instacart figure for how much a household of four spends on groceries, the researchers estimated that a similar difference over a year could amount to roughly $1,200. Instacart strongly disputed that annual extrapolation and said the limited tests should not be treated as though a household would continually pay higher prices throughout an entire year.
The company also said the pricing tests were randomized and did not use personal information, demographics, shopping history or individual behavior to decide who received each price. Instacart ended the item price tests in December 2025. The company now says customers shopping for the same item at the same store location at the same time will see the same item price.

So, the investigation showed that Instacart shoppers could receive different prices during those tests. It did not prove that Instacart used personal profiles to select those prices. Researchers were finding customized shopping experiences long before today's AI-powered pricing systems.

In 2014, Northeastern University researchers studied 16 major retail and travel websites and found evidence of price discrimination or personalized search results on nine of them. CheapTickets and Orbitz offered reduced hotel prices to members. Expedia and Hotels.com steered some users toward more expensive hotels.

Home Depot and Travelocity personalized search results for mobile users. Priceline 会根据用户的点击和购买历史,对酒店搜索结果的排序进行个性化处理。不过,研究人员表示,这些不同的排序结果与价格并无相关性,因此他们没有将 Priceline 的这一案例归类为价格引导。研究人员还强调,他们针对这16家网站进行的大多数实验都没有发现价格引导或价格歧视。
Home Depot and Travelocity personalized search results for mobile users. Priceline personalized the order of hotel search results based on a user's history of clicks and purchases. However, the researchers said those different result orders did not correlate with price, so they did not classify that Priceline example as price steering. The researchers also emphasized that most of their experiments on the 16 sites did not uncover price steering or price discrimination.
2015年,ProPublica 发现,The Princeton Review 会根据客户所在的邮政编码,为其在线 SAT 辅导套餐设定不同价格。其 Premier 套餐的价格从6600美元到8400美元不等。ProPublica 发现,无论收入如何,居住在亚洲人口占比更高的邮政编码地区的人,被报价更高的可能性是其他人的1.8倍。
Then in 2015, ProPublica found that The Princeton Review charged different prices for an online SAT tutoring package depending on a customer's ZIP Code. Prices for its Premier package ranged from $6,600 to $8,400. ProPublica found that people living in ZIP Codes with larger Asian populations were 1.8 times as likely to be offered a higher price, regardless of income.
The Princeton Review 表示,其定价依据是各市场运营业务的成本和竞争状况。价格是按地理区域而非客户种族设定的。这个案例属于地域定价,而不是零售商为每位购物者单独设定价格。但这仍然表明,与居住地点相关的数据可能导致不同消费者群体获得不同的价格。
The Princeton Review said its pricing was based on the costs of running its business and competitive conditions in each market. It said its prices were set by geographic region rather than a customer's race. That example was geographic pricing rather than a retailer setting a unique price for each individual shopper. It still shows how data connected to where someone lives can lead different groups of consumers to receive different prices.
目前没有一种保证能获得网络最低价的万能方法。不过,你可以减少零售商、数据经纪公司和追踪公司能够与你关联的信息,同时让自己有更多方式比较不同的报价。
There is no guaranteed trick for getting the lowest online price. However, you can reduce some of the information retailers, data brokers and tracking companies can connect to you while giving yourself more ways to compare offers.
在登录零售商网站或会员账户前,先以未登录状态查看商品,然后再登录并比较价格或优惠。价格出现差异并不一定意味着个性化定价,会员折扣和其他促销活动也可能导致价格变化。同时比较这两种视角下的信息,可以让你在购买前掌握更多情况。
Look at a product while signed out before logging into a retailer or loyalty account. Then compare the price or promotion afterg in. A difference does not automatically mean personalized pricing. Membership discounts and other promotions can also explain a change. Still, comparing both views gives you more information before you buy.
如果你不需要零售商账户,可以考虑以访客身份结账。这样,本次购买就不会自动成为已登录购物记录中的另一笔记录。访客结账并不会让你匿名。零售商仍可能收到你的电子邮件地址、支付信息、收货地址、浏览器数据或设备信息等信息。
If you do not need a retailer account, consider checking out as a guest. That keeps the purchase from automatically becoming another entry in a logged-in shopping history. Guest checkout does not make you anonymous. A retailer may still receive information such as your email address, payment details, shipping address, browser data or device information.
当网站提供相关选项时,请拒绝可选广告和跟踪 Cookie。该网站可能仍需使用必要 Cookie,以支持购物车、安全和支付等功能。拒绝可选 Cookie 主要能减少部分跟踪和广告活动。
When a website gives you the choice, reject optional advertising and tracking cookies The site may still need essential cookies for things such as your shopping cart, security and payment. Rejecting optional cookies mainly reduces some tracking and advertising activity.
零售商只是个人信息来源之一。数据经纪商和人物搜索公司会从众多来源收集信息,并将其整合成个人画像。美国联邦贸易委员会的研究发现,定价系统可能会纳入第三方数据,包括来自数据经纪商的数据。减少这些公司能够获取的信息,或许能缩小你整体数据足迹的一部分。但这并不能保证你获得更低的价格,也不能阻止零售商使用直接从你那里收集的信息。
Retailers are only one source of personal information. Data brokers and people-search companies collect information from numerous sources and combine it into profiles. FTC research found that pricing systems can incorporate third-party data, including information from data brokers. Reducing what's available through those companies may shrink one part of your broader data footprint. It does not guarantee a lower price or prevent a retailer from using information it collects directly from you.

It does not make you anonymous. Websites may still see information such as your IP address and information you provide directly. The FTC specifically points to private browsing as one step consumers might use when trying to avoid higher personalized prices.
请寻找“拒绝出售或共享我的个人信息”“您的隐私选择”等选项,或针对性广告控制选项。可用选项取决于零售商以及你所在地区适用的隐私法。
Look for choices such as Do Not Sell or Share My Personal Information Your Privacy Choices or controls for targeted advertising. The options available depend on the retailer and the privacy laws that apply where you live.
查看哪些购物应用可以获取你的精确位置。如果某款应用不需要你的确切位置,请考虑将位置权限改为大致位置或关闭位置访问权限。请注意,网站和应用仍可能通过其他信息(包括你的 IP 地址)推测出你的大致位置。
Review which shopping apps can access your precise location. If an app does not need your exact location, consider switching to approximate location or turning location access off. Keep in mind that websites and apps may still estimate your general location from other information, including your IP address.
你的手机可能允许你限制哪些应用可以在其他应用和网站中跟踪你的活动。关闭不必要的跟踪可以减少部分第三方数据收集,但这并不能阻止零售商使用你通过其应用、网站或账户直接提供的信息。有关 iPhone 和 Android 的分步操作指南,请参阅我们的数字隐私提升指南。
Your phone may let you limit how apps track activity across other apps and websites. Turning off unnecessary tracking can reduce some third-party data collection. It will not stop a retailer from using information you provide directly through its own app, website or account. For step-by-step instructions on iPhone and Android, see our guide to improving your digital privacy.
Cookie 可以帮助网站在你再次访问时识别出使用的是同一浏览器。清除 Cookie 可以删除其中一些已存储的标识符。不过,其他跟踪方式仍可能识别你的设备,而重新登录账户会使你的活动与该账户重新建立关联。
Cookies can help websites recognize the same browser when you return. Clearing them can remove some of those stored identifiers. However, other tracking methods may still recognize your device, andg back into an account reconnects your activity to that account.
进行高价购买前,请查看零售商的网站和应用,然后将同一件商品与其他卖家的报价进行比较。你发现的价格差异可能有一个简单的解释,但货比三家能让你更清楚地了解目前可选的价格。
Before making an expensive purchase, check the retailer's website and app. Then compare the same product with other sellers. Any difference you find may have a simple explanation, but comparison shopping gives you a better picture of the available prices.
对于价格历史服务涵盖的商品,请查看今天的优惠是否真的低于近期价格。零售商的促销横幅只能告诉你它想宣传的内容,而历史价格能为你购买前提供更多参考。
For products supported by price-history services, check whether today's deal really is lower than recent prices. A retailer's sale banner only tells you what it wants to advertise. Historical pricing can give you additional context before you buy.
更低的价格可能以加入忠诚度计划、订阅、自动续订或作出其他承诺为条件。请确保计入这些条件后,该优惠确实能为你省钱。
A lower price may require a loyalty membership, subscription, automatic renewal or another commitment. Make sure the offer actually saves you money after those conditions are included.
VPN 可以隐藏互联网服务提供商分配给你的公共 IP 地址,并将其替换为 VPN 服务器的地址。这样,你基于 IP 判定的位置可能会显得不同。美国联邦贸易委员会(FTC)特别将使用 VPN 列为消费者在担心个性化价格时可能尝试的一种方法。VPN 无法删除你的零售商账户、购买历史、Cookie,或某款应用已获准访问的位置信息。网站还可能利用其他信号识别你。
A VPN can hide the public IP address assigned by your internet provider and replace it with the address of the VPN server That can make your IP-based location appear different. The FTC specifically lists VPN use as something consumers might try when they are concerned about personalized prices. A VPN cannot erase your retailer account, purchase history, cookies or location information that an app already has permission to access. Websites may also use other signals to recognize you.
如需了解最佳 VPN 软件,请参阅我的专家评测,了解适合 Windows、Mac、Android 和 iOS 设备、可用于私密浏览网页的最佳 VPN。真正让我关注的是,如今网上购物时,可能会有大量信息被用于决定我们看到的内容。我们没有证据表明每家零售商都在暗中为每个人设定不同价格,看到两个不同的价格也不能自动证明是个人数据导致了这种差异。
For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices at What gets my attention here is how much information can now go into deciding what we see when we shop online. We do not have evidence that every retailer is quietly setting a different price for each person, and seeing two different prices does not automatically prove personal data caused the change.
我们确知的是,企业拥有能够利用位置、浏览行为、购物历史及其他信息来调整价格、折扣和商品排名的技术。我的建议是,在购买前比较价格,尽量减少不必要的追踪,不要想当然地认为屏幕上最先出现的报价就是可获得的最佳价格。你交出的非必要信息越少,用来构建详细购物画像的数据也就越少。
What we do know is that companies have technology capable of using location, browsing behavior, shopping history and other information to shape prices, discounts and product rankings. My advice is to compare prices before you buy, limit tracking you do not need and avoid assuming the first offer on your screen is the best one available. The less unnecessary information you hand over, the less there is to feed into a detailed profile about how you shop.
