在经济密度较高，距京杭运河和黄河较远，距海岸线较近，年均温、河网密度和人均地区生产总值变化率较低的地方，城市扩展和耕地丧失的发生率较大。

Urban expansion and farm loss happen more frequently where economic density is higher , distances to canal and yellow river are further , distance to coastal line is nearer , and annual average temperature , hydrological density and rate of change of Per Capita GDP are lower .

工业经济活动密度每增加1%，TFP增长率便下降0.6%，说明我国现阶段各城市因过度发展工业引起的产业结构失衡对全要素生产率带来了负面影响。

If density of industry activity increases 1 % , TFP growth will decrease 0.6 % . This means industry of cities is unduly developed , and it begets a bad economy structure , adversely affecting productivity .

另一家研究公司——伍德麦肯兹公司（WoodMackenzie）的保罗？？麦康奈尔（PaulMcConnell）已经指出，中国若想在2020年前实现其经济碳密度降低四成的承诺，该国的天然气需求量就将远远高于现有预期。

Paul McConnell of Wood Mackenzie , another research firm , has argued that for China to meet a pledged 40 % reduction in the carbon intensity of its economy by 2020 would require a lot more gas than currently expected .
