Been to the remaining capacity: pain but necessary

Since 2008, as part of the ten measures aimed at boosting domestic demand and driving economic growth, China embarked on a massive infrastructure expansion. This included large-scale projects such as roads, bridges, and airports. For many regions, this marked the "starting gun" for development, sparking rapid urbanization and industrialization. However, the long-term consequences of these investments have since become a topic of intense debate. Over the past five years, discussions about the effectiveness of the 2008 stimulus package have continued to grow. The reflection on the so-called "4 trillion yuan" economic stimulus program has not yet subsided. By 2012, a new wave of investment boom was emerging, raising concerns once again about overcapacity and unsustainable growth. Things began to shift in June 2013 when Premier Li Keqiang chaired a State Council meeting, emphasizing the need to address overcapacity. He called for targeted mergers and acquisitions (M&A) loans for companies integrating excess capacity and strictly prohibited new credit for illegal construction projects with serious overcapacity issues. This signaled a turning point in China’s approach to managing its economy. The term “4 Trillion 2.0” has been widely used to describe the renewed investment trend, though officials have denied it. Nevertheless, the pattern seems similar to the 2008 stimulus. Many of the approved projects still focus on traditional sectors like steel, infrastructure, and energy—areas that were heavily invested in during the previous round. For example, in May 2012, the National Development and Reform Commission (NDRC) approved major projects such as the Zhanjiang Iron and Steel Base and the Guangxi Fangchenggang Steel Base, both with massive investment scales. These developments suggest that the government is still prioritizing heavy industries despite warnings about overcapacity. By 2012, the problem of overcapacity had become more pronounced. Key sectors like automobiles and real estate were experiencing downturns, and product prices were falling due to surplus supply. Corporate profits declined, and investment slowed down significantly. According to the IMF's 2012 Country Assessment Report, China’s capacity utilization rate dropped from around 80% before the 2008 crisis to just 60% in 2011, further declining to 54.7% by early 2013. This cycle of overinvestment and overcapacity has led to repeated calls for structural reforms. While the central government has repeatedly emphasized the elimination of outdated production capacity, actual progress has been slow. Local governments, driven by the pursuit of GDP growth, have often continued to push for new projects, contributing to redundant construction and inefficiency. In recent years, the language around capacity issues has evolved. From “resolutely eliminating backward production capacity” to “strictly controlling investment in overcapacity industries,” the focus has shifted toward sustainable development. Yet, the data tells a different story: capacity utilization rates have continued to decline, indicating that the problem remains unresolved. Addressing overcapacity is now a critical challenge for China’s economy. The recent policy adjustments, including M&A support and stricter lending rules, are steps in the right direction. However, without deeper structural reforms, the country may find itself caught in another cycle of overinvestment and economic imbalance.

SPR rubber Vertical Slurry Pump

Naipu SPR rubber Vertical Slurry Pumps are vertical, centrifugal slurry pumps submerged in sump to work.They are designed for delivering abrasive,large particle and high density slurries.These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.Wet parts of type NP-SP pump are made of abrasion-resistant metal. All parts of type NP-SP(R) pump immersed in liquid are lined with rubber outer liner.They are suited to transport non-edge angle abrasive slurry.

Typical Applications---

Sump drainage washdown
Floor drainage
Mill sumps
Carbon transfer
Monitoring

Magnetite mixing
