While much of Europe follows the lead of President François Hollande of France in calling for jointly issued debt, or euro bonds, as the solution to Europe’s troubles, a vast majority of Germans reject the idea.

To German ears, the demand for euro bonds sounds less like a technical solution to the crisis than a way to use Germany’s good credit rating to push off difficult but necessary reforms.

“You don’t entrust your credit cards to anyone if you can’t control the spending,” said Jens Weidmann, president of the Bundesbank, Germany’s central bank, in an interview Friday with the French newspaper Le Monde.

“Pooling debt is not the right tool for growth,” said Mr. Weidmann, a former economic adviser to Chancellor Merkel. “This would pose both legal and economic problems. I don’t think we’ll be successful in trying to resolve the debt crisis with more debt outside the regular budgets.”

Ms. Merkel dominated the political decision-making in Europe for much of the crisis, culminating in the signing in March of the fiscal pact to reduce budget deficits by 25 of the 27 European Union countries. But countries like Greece and Spain have underperformed economically and been unable to rein in their deficits as quickly as promised.

Mr. Hollande’s victory this month over his predecessor, Nicolas Sarkozy, and his aggressive support of new spending measures to increase growth have put Ms. Merkel on the defensive. The long-awaited growth plan for Europe from Ms. Merkel is being debated in the Chancellery and the ministries of finance and economics. The answer from Berlin is not so much, as Ms. Merkel is fond of saying, “more Europe,” and it is definitely not substantially more money, but instead more Germany. It is clearer than ever the degree to which Germany wants to remake Europe in its own image.

The magazine Der Spiegel reported that a six-point plan is in the works that includes incentives for midsize companies, a loosening of protections against firing for workers, special economic zones and even a version of Germany’s system of dual training divided between vocational school and hands-on work at companies. State-owned enterprises would be sold in a process similar to that of the Treuhand, the agency that helped privatize East Germany.
