We analyze waste generation differences across Spanish regions by studying the evolution of two complementary indicators: municipal solid waste per unit of GDP as well as in per capita terms. To that end, we apply the recent statistic developed by Phillips and Sul (2007) which allows us to test for the null hypothesis of convergence. In the present case, this hypothesis is equivalent to admitting that the waste generation follows a similar path across the Spanish regions. Our results lead us to reject this hypothesis, which implies that Spanish regional waste generation is quite heterogenous and exhibits several patterns of behavior. We observe that the northern regions exhibit the lowest waste ratios while the insular and Mediterranean coast regions have the highest waste generation. This different behavior is also explained by some socioeconomic factors. Per capita income, environmental spending and education level are helpful in this regard. The population dispersion and the number of years that a region has been governed by a left-wing party are also associated with lower levels of waste generation. Finally, we can also observe that the regions with the highest levels of waste generation are greatly dependent on the tourism industry. Then, strategies targeting the transit towards a more sustainable economy in Spain should take into account this fact. In particular, the adoption of methods for the reduction of the waste levels generated by tourism activities in these areas can be very useful.

通过研究两个互补指标的演变，我们分析了西班牙各地区的废弃物产生差异：单位GDP以及按人均计算的城市固体废弃物。为此，我们采用了Phillips和Sul（2007）开发的最新统计数据，该统计数据使我们能够检验收敛的零假设。在目前的情况下，这种假设等同于承认废物产生沿西班牙地区类似的路径。我们的结果使我们拒绝了这一假说，这意味着西班牙的区域废物产生方式非常异质，并且表现出多种行为模式。我们观察到北部地区的废物比率最低，而岛屿和地中海沿岸地区的废物产生量最高。社会经济因素也解释了这种不同的行为。人均收入，环境支出和教育水平在这方面有帮助。人口分散和该地区由左翼政党统治的年限也与废物产生水平较低有关。最后，我们还可以观察到废物产生量最高的地区在很大程度上取决于旅游业。然后，针对西班牙向更可持续的经济过渡的战略应考虑到这一事实。特别是，采用减少这些地区旅游活动产生的废物水平的方法可能非常有用。人口分散和该地区由左翼政党统治的年限也与废物产生水平较低有关。最后，我们还可以观察到废物产生量最高的地区很大程度上取决于旅游业。然后，针对西班牙向更可持续的经济过渡的战略应考虑到这一事实。特别是，采用减少这些地区旅游活动产生的废物水平的方法可能非常有用。人口分散和该地区由左翼政党统治的年限也与废物产生水平较低有关。最后，我们还可以观察到废物产生量最高的地区在很大程度上取决于旅游业。然后，针对西班牙向更可持续的经济过渡的战略应考虑到这一事实。特别是，采用减少这些地区旅游活动产生的废物水平的方法可能非常有用。针对西班牙向更可持续的经济过渡的战略应该考虑到这一事实。特别是，采用减少这些地区旅游活动产生的废物水平的方法可能非常有用。针对西班牙向更可持续的经济过渡的战略应该考虑到这一事实。特别是，采用减少这些地区旅游活动产生的废物水平的方法可能非常有用。
