     Since The Shale Gas Development Plan of 2011 - 2015 was issued by the government in March 2012, both supporters and opponents have never renounced arguing those shale gas related issues in terms of theoretical strategies, technical economy, safety and environment concerns, etc. Among those supporters, Mr. Zhang Kang suggests that we should learn from experience in CBM gas development and insists on the crucial importance of national policies [-see Natural Gas Industry, 2013, 33（4） ：18-23~. In view of this, we made an in-depth analysis of reservoir properties of coal beds, gas shales and tight sandstones. Contrary to Mr. Zhang, our conclusions were drawn as follows. First, the commercial production of shale gas depends on reservoirs rather than na- tional policies. Second, coal beds and gas shales have an unfavorable attribute of elastic deformation in their geological settings. Third, shale gas development is not cost-effective at all and will inevitably contaminate surface and subsurface water system. Fourth, the locations of shale gas plays superimpose with the discovered conventional oil or gas fields, so it is still a question if shale gas origins from shale or comes from the connected conventional oil or gas formations after fracturing treatment. And finally, how much on earth China boasts of the shale gas reserves is still in doubt. In summary, we consider that shale gas development may not the best choice for Chinese government at present.
