中文摘要：

江苏经济发展面临着下行压力加大、创新动力不足、部分行业产能过剩等风险隐患，如何通过“加减乘除”加快产业结构调整至关重要。近年来，江苏经济发展持续向好，产业结构明显优化，创新引领动力强劲，落后产能逐步淘汰，重点行业提档升级，但同时也存在产业层次仍然偏低、部分行业产能过剩、成果转化短板明显、制度创新尚需突破等问题。突出精准支持，增加有效供给；强化市场机制，削减低效产能；培育创新优势，倍乘驱动效应；深化制度创新，去除发展障碍等是江苏产业结构调整的应对之策。

英文摘要：

The economy of Jiangsu is at the risk of increasing economic downward pressure,lack of innovation power, and excess capacity in some industries. It＇s essential to find out how to speed up industrial restructuring by ＇ add, subtract, multiply, divide＇ strategies. After many years of development ,the economic scale has been continually enlarged, industrial structures have been obviously optimized, innovations continuously appear, and major industries have been upgraded. However, there are still some problems, such as the industrial level remains relatively low, some industries have excessive capacities, the achievement transformation is obviously weak, and the whole industries lack institutional innovations, etc. Jiangsu should have countermeas- ures of industrial adjustment, for example, highlight support in specific industries, add effective supply, strengthen the market mechanism, reduce poor efficiency industries, foster innovation advantages and innovation multiplier effects, deepen institutional innovationa and reduce development obstacles.
