Reading the 2026 Seoul Mayoral Election's 'Speed of Change'
The 2026 Seoul mayoral election may seem simple as a question of 'what kind of change do you want', but it is actually a competition over 'how fast will it change' and 'which areas will change first'. There are clear differences between the victory scenario of Democratic Party candidate Jung Won-o and the continuity of incumbent Mayor Oh Se-hoon. This article analyzes and compares the pace, speed, and priorities of Seoul city government changes under each candidate's election from the perspective of political data analysis by Shim Jae-woo, CEO of AI Election Solutions. General principles were covered in Part 1's comprehensive guide; this article focuses on the practical differences of 'how Seoul will change depending on which mayor is elected'.
First 100 Days: Real Estate vs. Urban Development, Who Moves First?
The first 100 days under Jung Won-o's election and Oh Se-hoon's re-election show a stark divergence in policy priorities. Candidate Jung Won-o has set real estate and housing issues as his top pledge and presents 'rapid on-site response' verified through his experience as Seongdong-gu Chief as his strength. Mayor Oh Se-hoon, on the other hand, is likely to prioritize continuity in digital twin, global city branding, and large-scale urban development projects.
Jung Won-o's 100-Day Roadmap:
Oh Se-hoon's 100-Day Roadmap:
Core Difference: Jung Won-o focuses on 'tenants, youth, alleyways', while Oh Se-hoon focuses on 'global city competitiveness and large-scale projects'. For Jung Won-o to accelerate redevelopment in real estate policy, he must also address tenant protection legislation, making rapid TF composition and legislative promotion key. Oh Se-hoon, meanwhile, only needs to focus on accelerating already ongoing large projects, so organizational change is minimal.
Years 1-2: When Policy Momentum Differences Become Apparent
Beyond the first 100 days, into years 1-2, significant differences emerge in how the two administrations allocate policy energy.
Jung Won-o's Years 1-2 Priority Tasks:
Oh Se-hoon's Years 1-2 Priority Tasks:
Comparative Analysis: Jung Won-o seeks to create change through new policy construction (new data platforms, new AI systems, new industrial activation models), which carries risk but is faster in terms of 'citizen perception'. Oh Se-hoon accelerates existing projects, which carries less risk but makes 'new change' harder to perceive. Policy performance for both may be significantly affected by real estate market booms or busts.
Years 2-3: The Crossroads of Seoul's Entire System Change
Mid-term years 2-3 is when initial pledges show tangible results. Here, the difference between the two candidates emerges as a fundamental difference in 'Seoul city organization culture and administrative philosophy'.
Jung Won-o's Expected Changes in Years 2-3:
Oh Se-hoon's Expected Changes in Years 2-3:
Key Evaluation Criteria: Jung Won-o is evaluated on 'changes citizens perceive in daily life' (real estate supply speed, AI complaint processing, alley revitalization). Oh Se-hoon is evaluated on 'urban infrastructure, global competitiveness, large project progress'. If Seoul's real estate prices rise in years 2-3, Jung Won-o may have an advantage; if they fall, Oh Se-hoon may have an advantage.
Overall 4-Year Term Evaluation: Who 'Changed Seoul More'
Looking at the entire tenure, the traces Jung Won-o and Oh Se-hoon leave on Seoul city government will be in completely different directions.
Jung Won-o's 4-Year Term Achievement Focus:
Oh Se-hoon's 4-Year Term Achievement Focus:
Comparative Conclusion: Jung Won-o is evaluated on 'quality of life change for Seoul citizens', while Oh Se-hoon is evaluated on 'urban infrastructure and global competitiveness'. Citizen preference depends on 'which value you prioritize more'.
Risks and Feasibility: Jung Won-o's Weaknesses, Oh Se-hoon's Challenges
Each candidate's pledge implementation has respective weaknesses.
Jung Won-o's Policy Execution Risks:
Oh Se-hoon's Policy Implementation Challenges:
Key Evaluation Points: For Jung Won-o, 'reliability of pledges' (can he really execute real estate policies quickly) is critical; for Oh Se-hoon, 'substantiality of results' (do large projects actually improve citizens' lives) is the core evaluation point.
FAQ: Jung Won-o vs Oh Se-hoon, Which Mayor Will Create Change Faster?
Q1: Who will resolve the real estate problem faster?
A: In the short term (1-2 years), Jung Won-o is likely faster. Jung Won-o can make rapid policy decisions linking the resolution of stalled redevelopment districts with tenant protection, and presents 'rapid on-site response' verified through his Seongdong-gu Chief experience as his strength. However, real estate is also tied to market conditions, interest rates, and central government policy, so Jung Won-o's will alone has limitations. Oh Se-hoon accelerates already ongoing large development projects, making it difficult to perceive 'new change' in the short term, but can produce supply expansion results in the long term.
Q2: What is the likelihood Seoul's daily life will improve faster?
A: Jung Won-o has higher likelihood. Jung Won-o already implemented daily life-oriented technologies like smart shelters, smart crosswalks, and smart safety systems in Seongdong-gu, and has pledged to expand these to all of Seoul. Such policies quickly create 'changes citizens directly perceive'. Meanwhile, Oh Se-hoon's digital twin, urban development, and global branding enhance 'city competitiveness', but daily change appears more slowly.
Q3: How will Seoul city organization culture change?
A: Jung Won-o is expected to transition to a 'field-centered, quick decision-making, citizen communication' culture. Oh Se-hoon seems likely to deepen 'technology-centered, long-term project, global strategy' culture. Jung Won-o emphasized rapid inter-departmental cooperation and on-site response in his district chief experience and is likely to apply this to Seoul city. Oh Se-hoon appears set to further advance the digital system and large project promotion system already built.

Jung Won-o vs Oh Se-hoon, Why Differences in Policy Promotion Environment Determine Implementation Speed
The difference in implementation speed between the two candidates is not simply a matter of will. Jung Won-o starts from a high-risk environment of 'new policy construction', while Oh Se-hoon starts from a relatively low-risk environment of 'deepening existing systems'. When Jung Won-o expands policies he successfully implemented in Seongdong-gu (smart safety systems, tenant protection policies, on-site response systems) to all 25 Seoul districts, variables multiply exponentially, including regional characteristics, district chief cooperation, and budget securing. This is the key point. Conversely, Oh Se-hoon's urban development projects have already completed permits or are underway, so only the relatively clear goal of 'acceleration' needs to be achieved. Therefore, if you want 'rapid change', initial perception is likely higher with Jung Won-o, but if you want 'stable results', Oh Se-hoon may be more certain.
District Cooperation Structure: How Quickly Will Jung Won-o's Policies Actually Spread?
Most of Jung Won-o's pledges presume active participation from 25 districts, such as 'customized industrial activation for 25 districts', 'expansion of living AI systems', and 'systematization of on-site response'. However, how quickly district heads will follow the Seoul city mayor's policies is a separate question. As Seongdong-gu Chief who took his own district as a model, Jung Won-o must present an 'incentive system' that can minimize policy conflicts with other district heads (e.g., customized industry budget allocation, performance-based authority delegation) for implementation speed to accelerate. For Oh Se-hoon, urban development, digital twin, and global marketing are mainly Seoul city-level projects, so district cooperation structure is less critical. Therefore, 'actual implementation speed' depends on how quickly Jung Won-o establishes cooperative systems with district heads, and this is the true comparison point with Oh Se-hoon.
Fiscal and Central Government Cooperation: External Variables That Determine Implementation Speed of Both Policies
Jung Won-o's real estate policies (tenant protection, resolution of stalled redevelopment districts, supply acceleration) heavily depend on central government's interest rate policy, deregulation, and fiscal project approval. For example, to resolve stalled redevelopment districts by supporting tenant relocation costs, Seoul city's burden alone is insufficient, requiring central government housing funds or special budgets. Oh Se-hoon's urban development projects also require central government cooperation, but since they 'accelerate' already-approved projects, new deregulation or budget requests are relatively minimal. Therefore, for Jung Won-o's policies to be implemented faster, central government cooperation is essential, and if impossible, Oh Se-hoon's existing projects are likely to proceed more stably.
Technology Construction vs Policy Implementation: Different Approaches Between the Two Candidates in AI and Digital Systems
Jung Won-o has pledged to newly construct a 'living AI administration system' (smart shelters, smart crosswalks, AI safety control). This requires massive initial investment to install sensors and data platforms across Seoul. Meanwhile, Oh Se-hoon's 'digital twin' started construction in 2021 and is currently operating in parts of Gangnam. Therefore, Oh Se-hoon can focus on 'enhancing and expanding' existing systems. In terms of the timing citizens perceive technological change, Jung Won-o may be faster (it takes over a year for new systems to reach citizens' daily lives), but in terms of 'technology completeness', Oh Se-hoon's existing system is more stable.
FAQ: Specific Questions Frequently Asked from Comparative Perspectives
Q1: Will Jung Won-o really solve the real estate and jeonse crisis problem faster?
A: Initial response (policy formulation, TF composition, deregulation proposal preparation) is likely faster with Jung Won-o. However, simultaneously promoting 'tenant protection' and 'supply expansion' requires multi-agency cooperation, and actual jeonse crisis resolution depends far more on macroeconomic variables like market interest rates and apartment prices. Oh Se-hoon accelerates already ongoing large housing supply projects (Han River waterfront redevelopment, GBC, etc.), so results (increased supply) are certain but perception timing is later.
Q2: Who will create changes citizens can feel within 100 days?
A: Jung Won-o. Jung Won-o is expected to rapidly pursue organizational and policy changes like 'expanding living AI systems', 'launching regional industrial activation TF', and 'reorganizing on-site response systems', and such changes can be perceived relatively quickly by citizens. Oh Se-hoon's 100-day tasks are 'acceleration' of existing large projects, so changes citizens can detect (e.g., increased construction speed, technology completion) are likely to appear later.
Q3: Which pledges will actually show results 1-2 years later?
A: Jung Won-o is likely to show 'initial real estate policy results' (partial resolution of stalled redevelopment districts, implementation of tenant protection systems) and 'expansion of smart safety systems' (expansion to major Seoul areas). However, the AI administration system is likely still in construction phase. Oh Se-hoon is expected to showcase 'urban development progress rates' (Han River waterfront redevelopment groundbreaking, GBC construction speed visualization) and 'digital twin enhancement' (emergence of public transportation optimization examples). Conclusively, Jung Won-o's years 1-2 is a 'verification phase of real estate policy credibility' while Oh Se-hoon's years 1-2 is a 'demonstration phase of existing project implementation speed'.
Concluding Remarks: Jung Won-o vs Oh Se-hoon, the Choice Is Not 'Speed of Change' but 'Type of Change'
When comparing Jung Won-o's election and Oh Se-hoon's re-election, many voters judge based on 'who will create change faster'. But the more precise question is 'what type of change do you want'.
Jung Won-o appears to rapidly pursue 'changes that directly reach citizens' daily lives' (real estate, safety, regional activation), with high initial perception but facing tasks of organizational restructuring and district cooperation. Oh Se-hoon is expected to deepen 'large project-type changes that enhance city competitiveness' (infrastructure, global branding, technology advancement), with high stability but later daily life perception.
The decision point is simple: "Choose Jung Won-o if you want rapid changes in real estate and daily life; choose Oh Se-hoon if you want completion of large urban infrastructure and enhancement of global competitiveness"—this is the choice that will greatly shape Seoul city government's 4-year term.
