Population Growth Slowdown Drags on Global Potential Economic Growth

In the grand landscape of the global economy, the population factor has always held a pivotal position. Historically, population growth and economic prosperity have often promoted each other. A large and continuously growing population not only provides an abundant labor force for economic development but also creates strong consumer demand, driving the continuous expansion of the economy. However, the current slowdown in population growth is gradually becoming a key factor dragging down global potential economic growth, profoundly influencing the trend of the world economy.

According to forecasts by international authoritative institutions, during the period from 2024 to 2029, the world's potential growth rate is expected to average 2.8% per year, and it will gradually decline thereafter. This data shows a significant gap compared with the past. In the decade before the global financial crisis, the average annual growth rate of the global economy reached 3.6%. Even in the decade before the COVID - 19 pandemic, the average annual growth rate was 3.2% (calculated by market weighting). Such a stark contrast intuitively demonstrates the weakening of the current world economic growth momentum, and the slowdown in population growth is undoubtedly an important factor that cannot be ignored.

Looking back over the past 50 years, the world's population growth rate has already halved, and it is now less than 1%. At the same time, economic expansion is also showing a downward trend. According to the United Nations' population projections, world population growth will stagnate in 2075. The slowdown in population growth directly restricts the expansion of the labor market. Take Japan as an example. Due to the long - term low fertility rate and population aging, the number of the labor force has been continuously decreasing, and many enterprises have to face the problem of labor shortages. When enterprises expand production scale and explore new markets, they often encounter difficulties in labor shortages, which undoubtedly restrains the economic growth rate.

In addition to the impact on the labor force quantity, the slowdown in population growth also interacts with the decline in productivity, leading to a slowdown in the process of globalization. With the stagnation of population growth, the vitality of innovation and consumer power have also declined, thus affecting the improvement of productivity. The decline in productivity has changed the competitiveness of countries in the global industrial chain and reduced the activity of trade exchanges. Goldman Sachs economists also regard this as an important reason for the slowdown in GDP growth. When population growth can no longer provide sufficient impetus for economic development, the engine of economic growth will gradually lose its former strong momentum.

"Global population control is one of the necessary conditions for long - term environmental stability." Although this view is reasonable to some extent and alleviates the pressure on resources and the environment to a certain extent, it is undeniable that population aging and slow growth have also brought a series of thorny problems. The most prominent ones are the continuously rising medical and retirement costs. In some European countries, such as Germany and Italy, the proportion of the elderly population is increasing continuously, and the social expenditure on medical security and old - age benefits has soared, accounting for an increasing proportion of fiscal expenditure. For many countries, this is undoubtedly a heavy financial burden, squeezing the investment and development space in other fields.

In the next decade, it is expected that more and more economies will need to deal with the severe economic challenges related to the aging population. These challenges not only include the above - mentioned issues of medical and retirement costs but also involve changes in the social consumption structure. The consumption propensity and consumption capacity of the elderly population are different from those of the young group. The elderly are more inclined to consume in fields such as healthcare and elderly care services, while the demand for some emerging consumption fields is relatively low. This may lead to a shrinkage in the market demand for certain industries, and the adjustment and transformation of related industries will require a large amount of time and resources.

Facing the many problems brought about by the slowdown in population growth, countries need to take active measures. On the one hand, increase investment in education and technology, improve productivity by enhancing the quality of the labor force and promoting scientific and technological innovation, and make up for the shortage of labor force quantity. For example, Finland has vigorously developed education, cultivated a high - quality labor force, and achieved remarkable results in the field of scientific and technological innovation. On the other hand, improve the social security system, rationally plan medical and old - age care resources, explore diversified old - age care models, and reduce the financial burden. At the same time, encourage childbirth in policies, introduce a series of measures conducive to family childbirth and parenting, such as providing birth subsidies and extending maternity leave, and gradually improve the population structure.

The slowdown in population growth dragging down global potential economic growth is a complex and long - term issue that requires the joint attention and efforts of all countries in the world. Only through the collaborative cooperation of all countries can we maintain stable economic growth and sustainable social development against the backdrop of changes in the population structure.
