Chungcheong Megacity: Is It Really Just for Daejeon? Understanding Heo Tae-jeong's Regional Cooperation Vision

As the 2026 local elections approach, the "Chungcheong Megacity" vision proposed by Daejeon mayoral candidate Heo Tae-jeong may feel unfamiliar at first. It's natural to wonder: "Isn't this just a development pledge for Daejeon alone?" or "Will this actually help citizens?"

Shim Jae-woo, CEO of AI Election Solutions, analyzed regional political data and compiled the 5 most frequently asked questions by newcomers trying to understand regional cooperation policies. This article is structured to address those misconceptions and questions. Through analogies and real case examples, we'll examine how Chungcheong Megacity actually works and why it matters to Daejeon citizens.

This is the most common misconception. "Since Sejong is the administrative capital, won't Sejong get stronger while Daejeon gets pushed aside?" This concern is understandable, but Heo's regional cooperation vision is the opposite structure.

Simply put, until now, the Chungcheong region has been trapped in a "Seoul-centric vertical economic structure." Products are made in Seoul, and money flows to Seoul. Sejong, Daejeon, South Chungcheong, and North Chungcheong each operate separately, competing only with each other. Candidate Heo's megacity vision aims to transform this into a "horizontal network economy."

The key is this:

•Sejong becomes the center of the central government, policy, and legislation as the administrative capital

•Daejeon plays the role of "technological implementation" of Sejong's policies through science, technology, and AI industries

•South Chungcheong handles actual production and exports through manufacturing and port industries

•North Chungcheong leads future new industries through biotech, semiconductors, and secondary batteries

These four don't compete with each other; instead, they form "one massive value chain." Daejeon KAIST's AI research → policy planning at Sejong government → production at South Chungcheong factories → connection with North Chungcheong's semiconductor industry. Each plays a different role while the overall economy grows.

One-line answer: Chungcheong Megacity's core is a "specialized alliance," not competition with Sejong.

The second misconception is that "megacity = administrative integration." It's like thinking Seoul, Gyeonggi, and Incheon become one city, but this is incorrect.

What Candidate Heo is proposing is not administrative integration, but rather network connection of economy, infrastructure, and policy. Each city maintains an independent administrative system while deepening transportation, logistics, information, and policy cooperation.

Real examples make this clearer:

Building Metropolitan Transportation Networks: Coordinating regional bus and railway policies between Daejeon, Sejong, and South Chungcheong. Currently, each local government operates separately, but linking them increases commuter traffic and population flow.

Sharing Industrial Data: AI research results from Daedeok Research and Development Cluster (Daejeon) → Sejong government policy establishment → application to South Chungcheong manufacturing. Instead of separate systems, one information flow.

Metropolitan Workforce Supply Networks: Talent produced by Daejeon universities → hired as Sejong civil servants → becomes industrial experts in South Chungcheong. Regional talent circulation.

This is similar to how multiple apps on a smartphone operate simultaneously on an OS. The apps don't integrate, but they cooperate on the same platform.

One-line answer: Regional cooperation's essence is "economic and infrastructure platform connection," not administrative integration.

The third question is very practical. "Regional cooperation sounds nice, but won't Daejeon's budget actually be spent for other areas in Chungcheong?" This is a valid concern.

In Candidate Heo's vision, this is designed as a "circular benefit" system—when Daejeon invests, the effects come back.

Here's an example:

Daejeon invests in AI economic capital infrastructure → Building data platforms connecting KAIST and Daedeok Cluster, supporting AI startups
↓
Sejong government applies this to policy → Administrative digitalization, smart city policy, AI-based civil petition processing
↓
South and North Chungcheong industries apply this to actual production → AI-based quality management, energy efficiency improvements
↓
As a result, Chungcheong GDP grows → Daejeon tax revenue increases → Improved welfare for Daejeon citizens

This isn't about "helping other areas"—it's based on the logic that "when the entire Chungcheong region grows, Daejeon automatically grows too." It's like how not just the city with a large corporation's headquarters benefits, but the entire supply chain prospers when the whole system develops.

One-line answer: Regional cooperation is not just Daejeon's investment, but "Daejeon's reinvestment through the growth of the entire Chungcheong region."

This is the fourth misconception. "Daedeok Research and Development Cluster has existed for over 40 years—so why would it suddenly become an AI economic capital?" is the question.

This is an important point. Daedeok R&D Cluster was facilities focused on "research." While there are excellent research papers and technology development, the part about "commercializing" it and creating an actual "money-flowing economy" was weak.

This is where Candidate Heo's vision comes in:

Research Outcomes → Commercialization Platform: Directly connect Daedeok Cluster's research with companies and startups. Move beyond simply publishing papers to actual product development and commercialization.

AI Startup Demonstration City: Transform Daejeon into a "space where new technologies are tested." For example, actually operate autonomous vehicles, AI robots, smart factories first in Daejeon.

Data Platform Creation: Utilize all of Daejeon's industrial, transportation, and welfare data as AI model learning materials. This itself becomes Daejeon's competitiveness.

If Daedeok Cluster was previously an "isolated research facility," Candidate Heo's vision is to transform it into an "AI technology factory for the entire Chungcheong region."

One-line answer: The core of AI economic capital is transforming Daedeok Cluster's "research achievements" into "commercialized economy."

The fifth question concerns "trust" as a politician. "Even if Candidate Heo makes this pledge, won't it all be abandoned when a different mayor comes in four years later?" This concern is understandable.

This question matters because regional cooperation is not a short-term pledge but long-term system building. For Candidate Heo's megacity vision to work properly:

Institutionalization: Establishing Chungcheong Metropolitan Alliance and permanent cooperation bodies → continues regardless of who becomes mayor

Physically Materializing Infrastructure: Metropolitan railways, data platforms, research networks → once built, they operate automatically

Legal Foundation: Special laws, contingency budgets, central government cooperation plans → less affected by political changes

Therefore, Candidate Heo's strength lies in his "previous mayoral experience." Because he has actually run city administration, he understands "how to design these systems so they actually work." This represents a realistic system design by an experienced person, not an idealistic pledge by a newcomer.

One-line answer: Regional cooperation must be designed as "institutionalized system for the entire Chungcheong region," not just one mayor's pledge, to be sustainable.

When understanding Candidate Heo's Chungcheong Megacity vision, the crucial point is that this is not just Daejeon's story. Sejong handles administration, Daejeon handles technology, South Chungcheong handles production, North Chungcheong handles new industries. The key is "connecting" each region's different strengths. When this happens, Chungcheong can become the "central axis of the nation's economy" like the Seoul metropolitan area.

Additionally, for this vision to become reality, system building is needed, not just pledges. Metropolitan transportation, data platforms, cooperation bodies, legal foundations. This is why Candidate Heo's previous mayoral experience is important.

Q1: Won't real estate prices skyrocket if Chungcheong Megacity actually happens?

A: There's a possibility of short-term appreciation in areas with improved metropolitan transportation. However, Candidate Heo's vision focuses on "creating industries and jobs," not just real estate development. If sustained economic growth through Daedeok Cluster-based AI industry, advanced manufacturing in South Chungcheong, and new industries in North Chungcheong materializes, housing prices would rise "stably" rather than rapidly.

Q2: There have been regional cooperation attempts before—why haven't they worked?

A: Existing regional cooperation efforts were mostly at a "loose consultation level." Each local government didn't want to lose control, and it never reached the level of investing actual budgets and personnel. What Candidate Heo is talking about is "institutionalization" like "permanent bodies, dedicated organizations, integrated data platforms." That's the difference.

Q3: As a Daejeon resident, will this pledge actually help me?

A: Help comes in stages. First, improved metropolitan transportation means shorter commutes and expanded living areas. Second, growing AI and technology industries increase youth jobs. Third, cooperation with Sejong government may provide policy-level support for Daejeon pledges (integrated care, "All Through Daejeon 2.0," etc.). Fourth, overall Chungcheong economic growth increases Daejeon's tax revenue and welfare budget.

| Item | Existing Regional Cooperation | Heo Tae-jeong's Vision | Core Difference |
|------|----------|------------|----------|
| Level of Cooperation | Loose consultation, event-focused | Institutionalized permanent bodies, integrated data platform | Self-operating system vs. repeated negotiation |
| Role Distribution | Each competing | Sejong (administration)·Daejeon (technology)·South Chungcheong (production)·North Chungcheong (new industry) | Network-type value chain vs. fragmented support |
| Investment Mechanism | One-time budget | Circular benefit structure (investment → results → reinvestment) | Sustainable growth model vs. temporary projects |
| Technology Base | Documentary cooperation | AI data platform-based policy linkage | Automation and optimization vs. manual coordination |
| Leadership | New politician's idealistic pledge | Experienced mayor's realistic system | High feasibility vs. risk of remaining a pledge |

Candidate Heo Tae-jeong's emphasis on Chungcheong Megacity in the 2026 local elections is clear. Currently, the Chungcheong region has different strengths yet fails to connect them properly. Candidate Heo's vision attempts to "connect these dots into lines."

"Did you think regional cooperation would only hurt Daejeon?" Not at all. When properly designed, Daejeon's AI technology and scientific infrastructure become the driving force to upgrade the entire Chungcheong region, and the benefits of that growth return fully to Daejeon. The key is how to automate this through "institutions and data."

In the 2026 local elections, when comparing Daejeon mayoral candidates' regional cooperation pledges, what makes Candidate Heo's megacity vision different is "previous experience" and "systems thinking." New vision is important, but we need an experienced perspective that understands "how to actually make it work in reality."
