The European Union’s Barcelona summit, which ended on March 16th, was played out against the usual backdrop of noisy "anti-globalizati0n’ demonstrations and massive security. If nothing else, the demonstrations illustrated that economic liberalization in Europe--the meeting’s main topic--presents genuine political difficulties. Influential sections of public opinion continue to oppose anything that they imagine threatens "social Europe", the ideal of a cradle-to-grave welfare state.
In this climate of public opinion, it is not surprising that the outcome in Barcelona was modest. The totemic issue was opening up Europe’s energy markets. The French government has fought hard to preserve a protected market at home for its state-owned national champion, Electricite de France (EDF). At Barcelona it. made a well-flagged tactical retreat. The summiteers concluded that from 2004 industrial users across Europe would be able to choose from com

[单项选择]"Europe needs to import to export. " That is the slogan of the European Commission’s new strategy for securing its economic place in the world, unveiled this week by Peter Mandelson, the European Union’s commissioner for trade. The soundbite, of course, gets the economics precisely backwards: exports are the price a country must pay for its imports; Europeans toil away making stuff for others to consume only so they can in turn get their hands on the fruits of foreign labours.
But the slogan does capture two awkward truths European exporters must now confront. First, only by offering to open its own markets can the EU hope to persuade foreign countries to open theirs. But with the collapse of the Doha round of trade talks, it is not obvious to whom the Europeans should make their offers. Second, European companies are now part of elaborate global supply chains. Clumsy efforts to protect some of them from foreign competition deprive others of the cheap inputs they need to thrive i
