Toward an Era Where Citizens Drive the Economy—The Future of the New Participatory Economy and International Systems Opened by S.I.R.
In our previous discussions, we began with the budding of a non-monetary economy and the S.I.R. (Shrinkage Incentive Regime) concept, which "gives value to shrinkage," emerged.
In this article, we further organize how S.I.R. will integrate into daily life as a
citizen-participatory economic model and simultaneously
expand into the framework of national and international systems across a multi-layered structure of life, business, community, nation, and international society.
■ 1. The Core of S.I.R.—A System Where Residents Return to Being the Protagonists of the Economy
The characteristic of S.I.R. is that the system is not imposed on citizens, but rather
the choices and actions of the citizens themselves become value and are visualized in the point.
The system is composed of the following four layers.
● (1) Participation
Residents participate voluntarily through municipal apps or social media.
Designed for "loose participation" with no coercion and the freedom to leave at any time.
● (2) Selection
The app presents suggestions for "shrinkage actions" based on daily life activities.
Commuting methods
Food choices
Home appliance settings
Digital usage time
Sharing and repair choices
AI suggests effortless options based on your lifestyle patterns.
● (3) Evaluation
The environmental impact reduced by each action is visualized as
NIAS (Negative Impact Avoidance Score).
CO2, water, and resource consumption are concretely quantified,
creating a structure where your contributions are clearly visible.
● (4) Rewards
SCC (Shrinkage Credit Certificate) is granted based on contributions,
which can be exchanged for local currency, preferential public services, corporate partnership discounts, and more.
This creates a flow of 'shrinking while gaining' naturally within daily life.

■ 2. Toward a society where 'small shrinkage' blends into daily life
What S.I.R. aims for is not environmental action based on 'effort.'
Rather, it is a lifestyle design where shrinkage is naturally realized as a result of your choices.
For example:
Walking or cycling to work
Using locally produced ingredients
Choosing repairs or second-hand items
Optimizing SNS and app usage
Automatic eco-settings for home appliances
Utilization of sharing services
The accumulation of these “small choices” will boost resource efficiency across the entire region.
Since data collection and measurement are automated by apps, value creation proceeds without increasing the burden of daily life.
■ 3. Redesigning the regional economy starting from local governments
S.I.R. will first be introduced through demonstration experiments at the municipal level. Medium-sized municipalities with populations of tens to hundreds of thousands are optimal.
Main elements of the demonstration
Scoring of degrowth behaviors
Reward granting and linkage with regional currency
Preferential treatment for public facilities
Collaboration with companies and universities
Expansion to school districts and shopping streets
Ensuring data transparency
UI improvement through resident co-creation
Through this,
“degrowth becomes regional value.” a new economic cycle is formed.
■ 4. Citizen choices change companies—The structure of “reverse-flow transformation”
The innovation of S.I.R. lies in inducing a bottom-up transformation where “citizen choices change corporate strategy.”
Once citizens start choosing “low-impact products and services,” companies will naturally be forced to change their axes of competition to match those needs.
New Corporate Competition Indicators
Longevity and ease of repair
Design based on sharing
Optimization of energy-saving performance
Transparency of raw materials
Zero-waste design
Environmental value throughout the entire lifecycle
If linked with tax systems and public procurement,
"manufacturing based on reduction" will become the mainstream.
This is different from conventional regulations; it is a
reverse-flow institutional design that flows from consumers to companies.
■ 5. "Reducing" becomes social value—Economic principles of the 21st century
With the climate crisis, resource constraints, and AI automation overlapping,
human society is facing the following facts.
Resources are finite
Productivity is already surging due to AI
Consumption has a physical limit
Markets are maturing
In this situation, it is difficult to measure the economy by "expansion."
Therefore, what S.I.R. proposes is,
Abundance through increase → Abundance through optimization
a shift in values.
Rather than growth to fill a deficit,
we are designing an era where achieving maximum satisfaction with the minimum necessary
is valued as a "social skill."
■ 6. Innovating Capital Circulation: The "Two-Tier Redistribution Model"
S.I.R. is not an eco-point system.
It is a foundation that redesigns the very nature of global, national, and local redistribution.
● (1) Global Redistribution
Common carbon taxes and resource taxes are collected from each country
and pooled into a "Global Resource Management Fund."
The funds are used for:
Support for vulnerable nations
Technology transfer
Bonuses for countries with significant reductions
and other global "degrowth incentives."
● (2) Local Redistribution
Domestically, carbon tax revenue and SIR scores are distributed to citizens on a sliding scale.
High-impact consumers: Appropriate burden
Low-impact consumers: High returns
A structure where those with lower incomes can more easily achieve high scores
This functions as a
"degrowth-version basic income"
and also contributes to correcting inequality.
■ 7. Institutionalizing for Corporations: LCA-based "SIR Corporate Score"
For corporations, an
LCA (Life Cycle Assessment)-based scorecovering the entire product life cycle will be introduced.
Scope:
Production
Distribution
Usage
Repair
Disposal
Reuse
Collection and Recycling
If this score is linked to ESG investment, tax systems, and public procurement,
companies will naturally shift toward high-score products.
■ 8. The Role of National and International Systems: Building a Common Foundation
While citizen-led, it must be backed by
design support from national and international organizations.
International Level
Degrowth Economy Guidelines
Standardization of International LCA
Operation of Global Resource Management Funds
Standardization of Degrowth Accounting
National Level
Redesign of Tax Systems
Digital Infrastructure Integrated with Life Logs
Cross-ministerial platform
Provision of the "Degrowth Chart" app
With these in place, citizens, companies, nations, and international organizations can
share the "value of degrowth" using the same scale.
■ 9. Conclusion: A Citizen-Led New Economy Changes the World
What S.I.R. aims for is not merely environmental policy.
Returning the subject of the economy to citizens—a shift at the civilizational level.
Citizens choose,
Citizens are evaluated,
Citizens move companies,
Citizens nurture systems,
Citizens create stability under resource constraints.
Once this structure takes root,
we will be liberated from an "economy that cannot be maintained without expansion," and
can transition to a next-generation economy where sustainability and happiness coexist.
