In order to push industrialization, to promote sustainable development, to reach energy-saving and emission reduction and to improve energy efficiency, this paper combines static analysis with dynamic analysis to measure energy efficiency of industrial enterprises in Heilongjiang province. Based on Heilongjiang's 13 cities, this paper uses industrial panel data of 2013 to 2018 and data envelopment to evaluate industrial energy efficiency with environmental factor considered in Heilongjiang province. The result shows a rising industrial efficiency, mainly contributed by technical advances and improved management. Geographically, the energy efficiency is not balanced, highest in the western, followed by the central and low in the eastern. Decomposition of the total element variables may suggest the improved technical efficiency be the major factor. Redundancy is used to measure the saving potential of industrial input elements, and measurement of redundancy from gas and air emission provides references for Heilongjiang to make objectives in emission reduction.

Water problem has hampered China's sustainable development in economy and society. This paper uses CNKI's Index functionto review Chinas water resource research from 146 pieces of papers funded by National Natural Foundation of China and Social Science Foundation. Five popularities are summarized, loading capacity, security, ecology, virtual water and water footprint, and their representative theories, evaluation methods, research domains and trends are also reviewed. There are three trends in China's water resources research, cross research in water resources, complete research framework in water security and ecology, and evaluation innovation in mature research domains.

This paper makes a case study of Xinghua city, determines land utilization division indexes in location and function based on macroscopic land utilization, agricultural lands, construction lands, and unutilized lands, applies cluster analysis to divide 34 towns within Xinghua city into 4 divisions: western ecological maintenance zone, urban core functional zone, southern key construction zone and central modern agricultural zone, which can provide a reference for the sustainable growth of lands and harmonious social and economic development in Xinghua city.
