Abstract By using DEAMalmquist index, this paper has studied the changes of total factor productivity and its decomposition item of listed companies of strategic emerging industries from the dimension of influencing factors, time series and growth pattern in Yangtze River Delta from 2007 to 2015.And this paper has performed a convergence test by using σ convergence equation and absolute β convergence equation between different types of enterprises. The research result shows that: The declining trend of total factor productivity of strategicemerging industries in Yangtze River Delta derived from the reduced technology efficiency level, the whole industry shows a lowend development trend that both pure technology efficiency and scale efficiency are low; According to the two dimensions of industry highend, The listed companies of strategic emerging industry in Yangtze River Delta are divided into three different types: Efficient growth companies, Extensive growth companies, Miserable growth companies. The differences of growth pattern between different types of enterprises are striking, so it is necessary to choose an appropriate highend development path; The total factor productivity and its decomposition item of listed companies of strategic emerging industries in Yangtze River Delta tend to converge significantly, the differences between enterprises will gradually narrow and eventually tend to the same steadystate level.
