Reform of China’s trade regime had four major dimensions: increasing the number and type of enterprises (eligible to trade in particular commodities); developing the indirect trade policy instruments (that were absent or unimportant under the planning system); reducing and ultimately removing the exchange rate distortion; and reforming prices/ so that they could play a role in guiding resource allocation. These reforms of the trading system were inextricably linked with reform of the enterprise sector to allow indirect regulation through market-determined prices to replace direct regulation of enterprise output through the planning system.
 
参考译文
中国的贸易体制改革涉及四个主要方面：增加经营特殊商品企业的数量和类别；拓展在计划经济体制下几乎不起任何作用的间接贸易政策手段；减少乃至最终消除汇率干扰以及实行价格体系改革以使其在资源配置中发挥作用。与贸易体制相关的这些改革与企业界的改革密切相关，目标是通过市场价格实行间接管理，从而取代计划经济体制下对企业产出的直接管理。
