Advertorial慕尼黑国际博览集团：领跑全球贸易2013年已过半，世界经济低增长、高风险的态势没有根本改变。

发达经济体复苏势头出现分化。

美国房地产市场、就业市场、股票市场均有所改善，制造业的国际竞争力部分得以恢复，但自动减支机制在一定程度上拖累经济增长。

欧洲金融市场稳定性增强，但经济陷入二次衰退，财政整固和一体化建设的阻力上升。

日本政府推出财政刺激、量化宽松、经济增长战略组合的“安倍经济学”，提振了企业和消费者信心，但可持续性面临考验。

新兴市场和发展中国家继续温和增长，一些新兴大国工业生产出现放缓势头。

IMF预计，2013年全球经济增长3.3%，其中发达经济体增长1.2%，新兴市场和发展中经济体经济增速温和回升至5.3%。

在此背景下，全球贸易的重心继续向新兴市场和发展中经济体倾斜，而在全球贸易中扮演平台角色的慕尼黑国际博览集团，又将如何展现出自己积极的一面？加强品牌国际化，提升行业竞争力作为一家全球知名展览企业，慕尼黑国际博览集团（以下简称“慕尼黑展览”），一直有着自己明确的宗旨和愿景。

慕尼黑国际博览集团总裁兼首席执行官狄克思（Klaus Dittrich）先生接受《经理人》专访时表示：“进一步的国际化、加强我们在国际竞争中的领先水平是我们集团策略中的重要一环。

中国国际工程机械、建材机械、工程车辆及设备博览会（bauma China）是我们集团强势品牌输出的典范：集团在慕尼黑举办bauma品牌展会，同时也在快速发展的地区开发同品牌展会。

公司在印度也举办bauma展会，9月还会在约翰内斯堡开展新的bauma Africa 展览。

我们希望能将海外销售份额再提高50%。

除战略目标之外，狄克思进一步强调了慕尼黑展览在全球贸易中扮演的平台化的关键地位：“慕尼黑国际博览集团拥有非常强的展会品牌。

通过这些国际领先平台，我们的客户可以在第一时间展示自己的重要创新。

每位参与者都有机会领略最新的市场趋势，也能在这里找到合适的合作伙伴。
