中国与学生母国的购物情境

Put the same hoodie in two cities and the purchase stops looking like one behaviour. In Shenzhen a student opens a mini-program from a chat, pays with a mobile wallet and receives the parcel the same day. In Nairobi her cousin opens a marketplace app, waits for an SMS, walks to an agent, inspects the item and pays cash. The product is identical; the sequence is not. This lesson calls that sequence the shopping context: who buys, where the purchase happens, which device is used, how payment is made, how the goods arrive, and whether the buyer trusts the seller enough to pay.

The six elements are a checklist, not a theory of culture. Who buys covers income, age, household and whether the buyer is a consumer or a small business. Where covers the physical market, the mall, the app, the social feed or the chat group. Device covers phone model, screen, data plan and page speed. Payment covers wallet, card, bank transfer, cash on delivery and credit. Delivery covers parcel networks, pickup points, agents and same-day couriers. Trust covers reviews, platform guarantees, inspection rights and the return address. Change any one and the same page can convert in one market and fail in another.

China's context is unusually integrated. Section 2.5 defines mobile commerce as transactions on wireless handheld devices and explicitly says it can be B2B, B2C or C2C. That sentence matters: mobile commerce is a device dimension, not a fourth transaction type beside B2B, B2C and C2C. The same B2C sale can be mobile; a B2B order can also be placed on a phone. The textbook reports that global retail m-commerce reached almost US$2.8 trillion in 2020, growing 32%, and forecasts almost US$4.5 trillion by 2024 (Figure 2-10, eMarketer data). Those are global retail figures, and the second number is a forecast, not a result.

On top of the device sits an integrated stack. Payment apps such as Alipay and WeChat Pay let users pay without swiping a card; social platforms added buy buttons; mini-programs let a retailer offer catalogue, checkout and service inside a chat app; and dense parcel and same-city delivery networks make short promises credible. The textbook describes these pieces separately under mobile and social commerce. The label “super app” is this lesson's shorthand for an app that bundles messaging, payment, services and shopping. The analytical point is not the label but the integration: discovery, payment, delivery and service sit in one place, so the customer rarely leaves the phone.

Many home markets assemble the same pieces differently. In Kenya, M-PESA is a mainstream way to send and receive money, and the Communications Authority reported 45.36 million mobile-money subscriptions and 416,994 registered agents in the first quarter of 2025. Pickup is normal: Jumia's own rural report describes more than 300 pickup points and over 26,000 JForce agents in Kenya. In Bangladesh, a Dhaka survey found cash on delivery still dominant, while Bangladesh Bank reported 238.08 million registered mobile-financial-service clients, 89.38 million active accounts and 1,841,979 agents in February 2025. These are different starting points, not failures to become China.

Two conditions deserve separate attention. The first is data cost. When mobile data is prepaid and expensive relative to income, a heavy page is not a design preference; it is a barrier. A catalogue that loads in three seconds on a flagship phone may take far longer on a mid-range device, and every extra image is paid for by the user. The second is trust. A prepaid buyer risks money before seeing the goods; a cash-on-delivery buyer risks time and a possible argument at the counter. Reviews, platform guarantees, inspection at pickup and a local return address reduce different parts of that risk. Trust is a judgement about predictability, not a personality trait.

For the seller, context becomes a set of design and cost decisions. A mobile-first page needs compressed images, a short checkout and a payment method the buyer already uses. A delivery promise must match the network: next day is credible in a dense city and misleading where parcels move through agents. Returns must name an address the buyer can reach. The unit economics change too. In a teaching simulation, a US$18 cash-on-delivery order with US$3 forward freight and a 20% refusal rate carries an expected logistics cost of US$3.60 before packing, because one in five parcels makes a return trip. A prepaid order does not carry that refusal leg. The numbers are illustrative, but the structure is real.

Numbers about the market need three labels: indicator, year and scope. Section 2.8 reports global retail ecommerce growth of 25.7% in 2020, 17.1% in 2021 and 12.2% in 2022, with about 2.56 billion online shoppers in 2022 growing only 3.4%. It also puts global retail ecommerce at about US$5.2 trillion in 2021. None of these is a cross-border figure. Global retail ecommerce includes domestic sales; China's domestic online retail is not China's cross-border exports; and a statement that ecommerce grew 12.2% does not mean that cross-border ecommerce grew 12.2%. A seller who drops the scope label turns a market statistic into a false promise.

The practical output of this lesson is a six-row table for each market, with the two largest gaps marked. That table is more useful than a list of national stereotypes because it points to specific changes: a lighter page, a wallet, a pickup option, a local return address, a different promise. It also prepares the next lesson. If context explains whether a purchase is possible, consumer decision stages explain how the buyer moves from need to purchase and beyond. Section 3.1.1 gives that path, and Lesson 10 walks it with a pair of shoes.
