When we say economic growth has become difficult, we usually think of recession or policy failure. But today's problem is not a matter of economic cycles—it's a matter of structure. More precisely, we have entered a situation where the very model of growth we have long taken for granted no longer works.
That growth model is called the linear economy.
The linear economy is simple. Resources are input, products are made, consumed, and discarded. The formula for growth was clear: produce more, consume more, and the economy grows. During the industrial era and the early days of globalization, this model worked powerfully. Resources were relatively abundant, environmental costs went unaccounted for, and technological progress translated directly into increased output.
But now those premises have collapsed.
The first limit is the resource problem. More important than resource depletion itself are price and volatility. Energy, critical minerals, and food are no longer stable inputs. Geopolitical conflicts shake supply chains, and securing strategic assets has become a matter of national security. The "stable input" that the linear economy assumed no longer holds.
This structural vulnerability was starkly revealed in the global semiconductor supply chain after 2020. The automotive industry reduced chip orders based on demand forecasts, and production shifted to other sectors. When demand recovered, supply could not be immediately restored. As a result, automobile production halted and vehicle prices surged. The problem was not a lack of technology. It was that the linear efficiency model—structured around one-way resource input measured only by output, with supply radically optimized for cost minimization—had lost its capacity to absorb shocks. Efficiency was maximized, but resilience disappeared. This is precisely where the vulnerability of the linear economy is exposed.
The second limit is the cost structure. The linear economy functioned without internalizing external costs. Environmental pollution, health costs, and social inequality were dismissed as side effects of growth. But now those costs have become an unavoidable reality. Carbon is being priced, ESG has become an investment criterion, and environmental burdens are being converted into fiscal and regulatory measures. We have entered a structure where growth leads directly to increased costs.
The third limit is the changing nature of technology. Technology continues to advance, but its effects no longer manifest solely as increased output. Digital technology improves efficiency but simultaneously disrupts existing industrial structures. Automation raises productivity but destabilizes employment and income structures. The platform economy dominates markets without owning assets. The era when technological progress meant physical production expansion has passed.
At this point, an important question arises.
Why do we still approach the problem of growth only in terms of "how much more can we produce"?
Output-centered thinking is the language of the linear economy. But today's key assets are increasingly non-linear. Data is not a resource that depletes with use. Technology expands as it combines. ESG performance becomes an asset of trust, not a cost. Networks amplify in value as they grow in scale. These assets cannot be explained by the linear input-output structure.
The most fundamental limit of the linear economy is not just about the environment or resources. It's that, despite the definition of growth having changed, we are still using the old formula. The more we push efficiency to extremes, the more vulnerable the system becomes; the more we externalize costs, the more social burdens accumulate. We face the paradox of becoming more unstable the more we produce.
Singapore's RIE2030 recognizes this mismatch. The document does not promise more inputs. Instead, it speaks of redesigning structures. It poses the question not of what to produce more of, but of what to transform and how. It recombines research, technology, and industry around national missions, treats digital as common infrastructure, and designs pathways for outcomes to generate economic ripple effects.
This is where the concept of the transformation economy emerges. It's not about circulation but transition; not about improving efficiency but restructuring value systems. Not reducing waste, but changing the economic status of undervalued assets. Not increasing output, but creating entirely different value from the same resources.
The linear economy has hit its limits. But this is not merely a signal of failure—it is a signal that a new grammar of growth is needed.
In the next installment, I will examine why the circular economy, which has been presented as an alternative to the linear economy, was not a sufficient answer even for Singapore. There is a reason why, despite moving beyond linearity, the structure still could not be changed. I will trace the boundary between what changes and what remains the same when we stay at circulation rather than transformation.
