国际货币基金组织最新调整了对全球经济前景的预期。[1]该机构预测2026年世界经济增长率为3%，相比4月份的预测值下调了0.1个百分点，这是继4月下调后的再度下修。[1]这一变化反映出地缘冲突和科技创新两股相反的力量正深刻影响各经济体的增长轨迹，导致全球经济增速呈现"冷热不均"的格局。
受地缘冲突冲击最严重的是中东和中亚地区的石油出口经济体。[1]沙特阿拉伯二季度国内生产总值同比下降4.8%，这是该国三年来首次出现经济萎缩，其中石油部门更是萎缩了24.7%。[1]整个中东和中亚地区石油出口经济体今年的增长率仅为0.5%，较2025年的3.1%大幅下滑。[1]发达经济体的表现同样承压。[1]美国二季度实际国内生产总值按年率计算环比增长1.5%，低于市场预期。[1]欧元区虽保持温和复苏态势，二季度环比增长0.4%，同比增长1%，但国际货币基金组织已将其2026年经济增长预测从1.1%下修至0.9%。[1]
与之形成鲜明对比的是，人工智能等新兴科技产业正为部分经济体注入新的增长动力。[1]中国上半年国内生产总值达69.6万亿元人民币，同比增长4.7%。[1]其中与人工智能相关的智能车载设备制造等行业保持30%以上的同比高增长，规模以上工业企业的集成电路产量同比增长23.1%。[1]韩国也因科技产业表现突出而获益，其二季度经济环比增长0.6%，超过市场预期。[1]
The International Monetary Fund has projected global economic growth of 3 percent for 2026, marking a downward revision of 0.1 percentage points from its April forecast [1]. This adjustment reflects the uneven performance of major economies under the influence of two competing forces: geopolitical conflict and technological innovation.
The Middle East has emerged as a significant drag on global growth. Saudi Arabia experienced its first economic contraction in three years during the second quarter, with GDP declining 4.8 percent year-over-year, driven by a 24.7 percent contraction in the oil sector [1]. The broader oil-exporting economies of the Middle East and Central Asia are now projected to grow just 0.5 percent this year, a sharp decline from 3.1 percent in 2025 [1].
Economic performance in developed markets remains subdued despite modest activity. The United States posted second-quarter real GDP growth of 1.5 percent on an annualized basis, falling short of market expectations [1]. The eurozone delivered 0.4 percent quarter-on-quarter growth and 1 percent year-over-year growth in the same period, prompting the IMF to downgrade its 2026 eurozone growth forecast from 1.1 percent to 0.9 percent [1].
By contrast, economies leveraging artificial intelligence and advanced manufacturing have demonstrated stronger momentum. China recorded first-half GDP of 69.6 trillion yuan, expanding 4.7 percent year-over-year, with AI-related industries such as intelligent vehicle equipment manufacturing maintaining growth rates exceeding 30 percent [1]. Integrated circuit production among China's industrial enterprises rose 23.1 percent compared with the same period last year [1]. South Korea also outperformed expectations with 0.6 percent quarter-on-quarter growth in the second quarter [1].
