Vietnam Market Research: A Nuanced Practice
For Clients
Most foreign companies think Vietnam is a small and simple market; this is their fatal mistake. In fact, the Vietnam market research landscape is nuanced, and its methods are uncoordinated.
Since 98% of local enterprises are SMEs that prioritize short-term sales over long-term research investment, and most domestic players operate without any formal market intelligence process, foreign entrants that emphasize Vietnam market research have a stronger foundation for their entry plan.
1. Vietnam Market Research Providers: A Shifting Landscape
Vietnam’s research provider ecosystem is not a clean, tiered market with clear roles. It has fragmented over time and restructured in ways that directly affect the quality and scope of what any single provider can deliver.
1.1. The hidden 3rd parties in your Vietnam market research contract
The most established part of Vietnam’s market research industry surrounds consumer studies. NielsenIQ, Kantar, for example, operate at the upstream level, however, actual execution of research projects runs through a complex chain of independent contractors.
Senior fieldwork managers exited corporations to run their own business, taking certain client relationships with them. What looks like a single agency engagement is often a coordinated network of specialized vendors, each handling a discrete part of the project. Understanding who is actually executing your research is a worthy task.
1.2. Strategically deep but narrow execution planning of Consulting Groups
Global consulting firms, including the Big 4, handle desk research and expert interviews internally. Their strategic output is rigorous, but their scope is deliberately focused on high-level analysis rather than execution-level market intelligence.
Historically oriented toward large-scale mandates, several of these firms have begun widening their coverage as the Vietnam market has compressed, but their model remains primarily strategic consulting, with research as a supporting function rather than a core deliverable.
1.3. The “On-the-surface” Vietnam market research agencies
A growing category of providers sits outside the traditional research agency model entirely.
Marketing and advertising agencies increasingly position themselves as research-capable, partnering with specialist vendors to deliver results.
“Mixer” firms offer everything from desk research to primary interviews, often through third-party execution. These providers can be useful for integrated mandates, but their research depth varies significantly and is rarely their primary competency.
In summary:
| Provider Type | Who They Are | Research Depth | Key Limitation |
| Traditional Research Agencies | Established firms operating upstream, with execution run through independent contractor networks | Strong for consumer/B2C studies | Actual execution is fragmented with multiple hidden sub-vendors behind a single contract |
| Global Consulting | Strategy-focused firms handling desk research and expert interviews internally | Rigorous but high-level analysis | Scope is deliberately strategic; market intelligence is a supporting function, not a core deliverable |
| Marketing / “Mixer” Agencies | Ad agencies and all-in-one firms partnering with specialist vendors for research delivery | Variable – rarely a primary competency | Ad agencies and all-in-one firms are partnering with specialist vendors for research delivery |
The practical implication: Vietnam’s research provider landscape offers real options, but each type is optimized for a specific business model – B2B or B2C, or a particular industry vertical. There is no dominant generalist, fragmenting its coverage, which means assembling a complete picture of any market typically requires working across multiple provider types simultaneously.
2. Data Collection in Vietnam Market Research: The Realities
2.1. Secondary Data: What Desk Research Can vs Cannot Tell You
Government portals including the General Statistics Office (GSO) and business associations such as VECOM and VAMA publish useful data, and they are the right starting points for orientation. The limitation is structural: public data in Vietnam is decentralized, frequently lags behind market movement, and rarely reaches the level of commercial granularity that investment or entry decisions require. Desk research in Vietnam establishes context; it does not validate strategy.
2.2. Primary Data: Where the Real Complexity Lives
2.2.1. Consumer research in Vietnam
It carries validity risks that are specific to the local context and that generic research methodology misses. Phone surveys (CATI) have effectively ceased to be viable:
- Low response rates and high scam skepticism among Vietnamese consumers make them operationally unreliable.
- Online-only survey approaches are similarly limited; at a minimum,
- One in-person session is required to produce data that holds up.
Beyond methodology, respondent behavior introduces distortion: survey participation is widely treated as a supplementary income source, incentivizing completion over honesty. Social desirability bias, avoiding negative responses, following perceived group consensus, and defaulting to neutral options, is observable.
Experienced local researchers design around these patterns yet those without deep Vietnam exposure typically don’t flag them until the data is already in.
2.2.2. Industry and expert research
Traditionally, this has depended almost entirely on personal networks and referrals. This model produces insight that is relationship-dependent, geographically narrow, and inconsistent in candor:
- Experts reached through informal connections may be reluctant to address sensitive commercial questions.
- The scope of any individual’s network rarely covers more than one or two sectors.
Even though the shift is recent and the coverage is still developing, structured expert network platforms (ENS) are beginning to change this dynamic in Vietnam, offering more reliable access, compliance framing, and quality consistency.
3. How ENS Supports Vietnam Market Research Across the Full Scope
The difficulty with Vietnam market research is that assembling accurate, commercially useful intelligence requires navigating a fragmented provider landscape, applying methodology that accounts for local validity challenges, and accessing expert perspectives through channels beyond personal referral networks.
ENS is built to consolidate that work. Arches’ dedicated recruitment team, locally embedded expert network, and Expert Solutions function, combining expert calls, desk research, and strategic analysis into integrated, actionable recommendations, allow businesses to operate across B2B and B2C contexts, across industries, and across the range of data collection methods that the Vietnam market research demands.
The companies that win in Vietnam right are those who get the market right, with a long-term vision in it.
