2015年是中国“一带一路”倡议全面实施的元年。“一带一路”建设有待财政政策发挥更大作用。

材料 经过数月的拉锯战，欧元区领导人峰会2015年7月13日达成协议，在希腊履行承诺实施改革措施的前提下，未来三年向希腊提供可能多达860亿欧元的贷款，以助其解决债务负担。希腊的财政问题由来已久，目前该国的财政赤字占GDP的比重已高达12%，远远超过欧元区设定的3%上限。我国2015年财政预算拟安排财政赤字1.62万亿元，比去年增加2700亿元，赤字率从去年的2.1%提高到2.3%。我国要重点实施“一带一路”、京津冀协同发展、长江经济带三大战略，同时更加注重保障基本民生，更加关注低收入群众生活，更加重视社会大局稳定。

结合材料和所学经济知识，分析希腊危机给我国正确发挥财政的作用提供了哪些启示。
