中文摘要：

丝绸之路经济带战略倡导中国加强与沿线国家投资合作，不仅能带动产业跨境转移与国际产能合作，而且有助于推进国内“三去一降一补”供给侧改革。中亚是中国向西开放的第一站与战略利益核心区，中国针对中亚国家不断扩大投资规模、拓展投资领域、丰富投资方式，有效促进区域产业转移与产能合作。然而，中国对中亚国家直接投资仍面临着投资环境不佳、经营管理不善、金融风险犹存以及地缘政治博弈等方面问题，制约区域分工合作向纵深方向发展。为此，需要进一步加强供给侧改革与丝绸之路经济带战略对接、提升对外投资合理性与有效性、发挥金融服务职能以及补齐发展短板，为扩大向西开放与推动供给侧改革创造有利环境。

英文摘要：

The strategy of the Silk Road Economic Belt advocates that China should strengthen the cooper- ation of investment with countries along the Silk Road. The cooperation will not only lead to cross - bor- der transfer of industries and international cooperation on production capacity, but also contribute to pro- moting domestic Supply -side Reform of＂ address overcapacity, reduce inventory, deleverage, lower costs, and bolster areas of weakness＂. Central Asian is the first station and the core area of strategic in- terests in China＇ s Westward Opening process. It will effectively promote regional transfer of industries and advancecooperation on production capacity if China keeps on enlarging investment scale to Central A- sian Countries, expanding investment area and enriching investment styles. However, the direct invest- ment from China to Central Asian Countries is faced with many problems which will restrict deeper region- al division and cooperation. We can examplify as follows：investment environment is poor, management needs to be improved urgently, financial risk and the geopolitical gamestill exist. Therefore, in order to create an environment for expandingWestward Opening scale and promoting the Supply - side Reform, the strategic connection between the Supply -side Reform and the Silk Road Economic Belt should be strengthened ,the rationality and validity of foreign investment should be justified, the role of financial services should be played sufficiently in order to bolster the weak spots.
