零售商及背后支持的公司可以收集有关您的地点、搜索内容、购买行为以及在线行为的信息。美国联邦贸易委员会表示,定价系统可以使用个人数据来估算个别消费者可能愿意支付的金额。这一担忧在华盛顿引起了严肃的关注。2026年8月19日,联邦贸易委员会发布了一项旨在规范个性化定价的执法政策声明。
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,它无法在所有情况下禁止这种做法,但如果公司未能清晰地告知消费者个人数据如何影响他们看到的价格,可能会违反联邦消费者保护法。那么,公司收集到的有关您的信息是否实际上会改变您看到的价格、折扣或产品呢?以下是研究表明的情况,以及在您下一次在线购物之前可以采取的措施。
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.

No technical experience is needed. MARYLAND MOVES TO BAN SURVEILLANCE PRICING IN GROCERY STORES You've probably encountered dynamic pricing already.
所谓动态定价,即根据供需状况、库存量、时间或地理位置等因素来调整价格。例如,当大量用户同时需要用车时,网约车费用便会上涨;机票与酒店价格也会随供需变化而波动。不过这并不意味着所有消费者看到的都是完全相同的动态价格——时机、地点及其他市场因素都可能迅速改变。
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.
个性化定价则有所不同:它借助消费者的个人信息来为其定制价格或优惠方案。因此,即便两人选购同一商品,也可能因各自的个人信息差异而获得不同的报价。
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“价格引导”现象:零售商可能保持实际价格不变,却调整商品展示顺序。美国联邦贸易委员会的研究显示,相关定价工具能利用消费者数据将特定商品置于更显眼的位置,甚至优先展示价格较高的商品。该委员会指出,消费者通常能接受因供需变化引起的价格波动,但若价格受到个人浏览习惯、购买记录或其他隐私信息的影响,则容易令人感到意外。
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.
联邦贸易委员会针对监控定价机制的研究发现:第三方定价服务商在协助零售商制定价格、促销策略或商品排序时,会使用极为详尽的消费者信息。这些信息包括:美国联邦贸易委员会(FTC)发现,其调查的定价中间商与至少250家客户合作,这些客户销售的商品和服务涵盖从杂货到服装的广泛领域。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相结合。
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.
这些外部来源可能包括忠诚度计划、预订系统、电子商务平台和数据经纪商。这并不表明所有这些客户都对个人实施差异化定价。但这确实表明,存在一种技术,可以将详细的消费者信息结合起来,并用于影响价格、折扣以及购物者看到的产品。
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.
一项较新的调查将优步(Uber)的案例与当今现实联系得更加紧密。2026年6月,《消费者报告》(Consumer Reports)发布了其对优步和Lyft定价机制长达数月的研究结果。该调查使用了174名志愿者,他们检查了美国境内超过40条路线。在其分析的30条虚拟路线中,《消费者报告》发现最低价格组与最高价格组之间的中位数差距为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.
在某些路线上,几分钟内查询同一行程的人收到了几个不同的价格。《消费者报告》设计了该研究,通过让志愿者在大致相同的时间检查路线,以减少基于时间的定价效应。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》的结论提出了异议。两家公司均表示,他们不使用个人数据来个性化基础车费,也不从事行为定价或监控定价。因此,该研究表明,乘客在相近时间查询类似行程时,可能会收到显著不同的价格。但这并不能证明这些价格差异是由个人数据造成的。你的网络服务提供商、各类网站及广告商能看到什么?
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.
在线杂货购物领域又出现了一个发人深省的例子。2025年12月,《消费者报告》、Groundwork Collaborative以及More Perfect Union联合发布报告称,他们在Instacart平台上测试的杂货商品中,近四分之三的商品对不同消费者标价不同。此次调查共涉及美国四个城市的437名消费者。
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之间相差幅度高达23%。研究人员还发现,购买相同商品组合时,不同消费者的支付总额平均相差约7%。根据Instacart提供的四口之家年均杂货消费数据,研究人员估算出这种价格差异若持续一年,消费者可能多支出约1,200美元。不过Instacart坚决否认这一年度推算结果,并指出这些有限的测试不应被视作消费者全年都会面临高价的情况。
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.
该公司还强调,价格测试属于随机安排,并未依据个人资料、人口统计信息、购物历史或个人行为来决定每位消费者获得的价格。
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.
2025年12月,Instacart终止了此类商品价格测试。目前该公司承诺:同一时间在同一门店购买相同商品的消费者将看到统一的价格。因此,此次调查仅能证明测试期间消费者可能遇到不同价格,但无法证实Instacart利用个人资料来决定价格。
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.
其实早在如今基于人工智能的价格体系出现之前,研究人员就已发现个性化购物体验的存在。2014年,东北大学的研究人员对16家大型零售及旅游类网站进行了研究,发现其中9家网站存在价格歧视或个性化搜索结果的现象。例如,CheapTickets与Orbitz会向会员提供更优惠的酒店价格;Expedia与Hotels.com则会将部分用户引导至价格更高的酒店;Home Depot与Travelocity也会为移动端用户定制搜索结果。
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根据用户的点击和购买历史对酒店搜索结果的排序进行了个性化处理。然而,研究人员表示,这些不同的结果排序并不与价格相关,因此他们并未将Priceline的例子归类为价格引导。研究人员还强调,他们在16个网站上的大多数实验并未发现价格引导或价格歧视。
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.
随后在2015年,ProPublica发现普林斯顿评论公司根据客户的邮政编码对在线SAT辅导课程包收取不同的价格。其Premier套餐的价格范围为6600美元至8400美元。ProPublica发现,居住在亚裔人口较多的邮政编码地区的人们,无论收入如何,被提供更高价格的可能性是其他地区的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.
普林斯顿评论公司表示,其定价基于其业务运营成本和各个市场的竞争情况。它表示,其价格是按地理区域而非客户的种族来设定的。这一例子属于地理定价,而非零售商为每个individual购物者设定唯一价格。然而,这仍然展示了与某人居住地相关的数据如何导致不同消费者群体收到不同的价格。
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.
没有确保能获得最低在线价格的捷径。然而,你可以在登录零售商或会员账户之前,先在未登录状态下查看商品。然后在登录后比较价格或促销活动。价格差异并不自动意味着个性化定价。会员折扣和其他促销活动也可能解释这种变化。尽管如此,对比这两种视图仍能在购买前为你提供更多信息。
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. 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.
如果您不需要零售商账户,不妨选择以访客身份结账。这样能避免此次购买记录自动添加到您的登录后购物历史中。不过以访客身份结账并不能让您完全匿名,零售商仍有可能获取您的电子邮箱地址、支付信息、收货地址、浏览器数据或设备信息。
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,请拒绝那些非必要的广告与追踪类Cookie。网站仍可能需要一些必要的Cookie来实现购物车功能、保障安全及完成支付流程。拒绝非必要的Cookie主要能减少部分追踪与广告行为。
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的来源之一。数据经纪商及各类个人信息查询公司会从众多渠道收集信息并整合为个人档案。美国联邦贸易委员会的研究显示,部分定价系统也会整合第三方数据,包括来自数据经纪商的信息。减少这些公司可获取的个人信息虽能缩小您整体的数据足迹,但并不能确保您获得更低的价格,也无法阻止零售商直接收集您的个人信息。
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.

使用隐私浏览窗口通常会开启一个独立的浏览会话,该会话不会调用常规浏览窗口的历史记录及大部分现有Cookie。不过这种方式同样无法让您完全匿名,网站仍可获取您的IP地址以及您主动提供的各类信息。美国联邦贸易委员会明确指出,隐私浏览是消费者试图规避个性化高价策略时可采取的措施之一。
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.
请留意网站上是否提供“禁止出售或共享我的个人信息”“您的隐私选项”或定向广告控制等相关选项。具体可选项目会因零售商及您所在地区的隐私法规而异。
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.
审查哪些购物应用程序可以访问您的精确位置。如果应用程序不需要您的确切位置,请考虑切换到大概位置或关闭位置访问权限。请记住,网站和应用程序仍可能根据其他信息(包括您的IP地址)估算您的大概位置。
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.
您的手机可能允许您限制应用程序如何跨其他应用程序和网站跟踪活动。关闭不必要的跟踪可以减少一些第三方数据收集。但这不会阻止零售商使用您直接通过其自有应用程序、网站或账户提供的信息。有关iPhone和Android的逐步操作说明,请参阅我们的数字隐私改善指南。
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可以帮助网站在您返回时识别相同的浏览器。清除Cookie可以移除其中存储的一些标识符。然而,其他跟踪方法可能仍会识别您的设备,重新登录账户会将您的活动与该账户重新关联。
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.
在进行昂贵的购买之前,请查看零售商的网站和应用程序。然后将同一产品与其他卖家进行比较。您发现的任何差异可能有简单的解释,但比较购物可以让您更好地了解可用的价格。
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.
对于受价格历史服务支持的产品,请检查今天的优惠是否确实低于最近的价格。零售商的促销横幅只会告诉您他们想要宣传的内容。在购买之前,历史价格可以为您提供额外的背景信息。
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.
更低的价格可能需要会员资格、订阅、自动续订或其他承诺。请确保在考虑这些条件后,该优惠确实为您省钱。
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能够隐藏互联网服务提供商分配给您的公网IP地址,并替换为VPN服务器的IP地址,从而让基于IP地址所判定的您的位置看起来有所不同。美国联邦贸易委员会特别指出,当消费者担心出现价格歧视现象时,使用VPN便是他们可能尝试的手段之一。不过,VPN无法清除零售商的账户信息、购买记录、Cookie数据,或是那些应用已获授权访问的位置信息。此外,网站还可能借助其他信号来识别用户身份。
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.
如需挑选优质的VPN软件,可参阅我撰写的专业评测文章——其中详细介绍了适用于Windows、Mac、安卓及iOS设备、能保障上网隐私的最佳VPN服务。令我尤为关注的是:如今有大量信息被用于决定我们在网购时能看到哪些内容。目前尚无证据表明所有零售商都在为每位顾客设定不同价格;即便看到不同价格,也不能直接断定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.
可以确定的是,各企业已具备相关技术,能够利用用户的位置、浏览行为、购物历史等信息来调整商品价格、折扣力度及排名顺序。我的建议是:购物前先比价,尽量减少不必要的个人信息追踪,切勿想当然地认为屏幕上显示的首个报价就是最优选择。您提供的无用信息越少,被用来构建个人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.
