Mayor Koch pledged yesterday to improve city services ''vastly'' as he formally announced his candidacy for the Democratic and Republican nominations for a second term. ''Today the delivery of services moves into first place,'' the Mayor told a crowded news conference at the New York Hilton Hotel. ''I say today that we must work in the next four years to improve the quality of life in this city, and we'll do it.'' The Mayor devoted most of his statement to pointing with pride at his record, notably ''the restoration of responsible fiscal management.'' But he also interjected often the element of running against his record on city services. He tried here to head off the opposition by promising even better times ahead.

France's new Socialist Cabinet decided today to impose an extra income tax on the very rich, a corporate tax on expense-account entertaining and other perquisites of top executives, higher taxes on luxury yachts and hotels and a ''windfall profits'' tax on banks and oil companies. The new taxes were part of a supplementary budget approved by President Francois Mitterrand and his Government at a four-hour meeting this morning. The budget must still be approved by Parliament. The revenue is to be used for a $1.2 billion package of expansionary economic measures also approved this morning, including establishment of 55,000 new Government jobs this year, a campaign against youth unemployment, construction of low-cost public housing for 50,000 families and nearly $500 million in subsidized Government credit to help companies in difficulty.

Five years ago, workers here at the oil refinery of Energy Cooperative Inc. were given a new lease on their jobs when the consortium of eight agricultural cooperatives bought the aging complex, an unprepossessing conglomeration of tanks, pipes and smokestacks, from Atlantic Richfield for $80 million. Its plan was to use Federal subsidy programs for small refiners to keep the plant alive and to supply relatively cheap fuel to farmers. But Energy Cooperative's dream ended up in Federal Bankruptcy Court in Chicago last month when the company filed for protection from creditors with claims of $432 million, becoming the first major corporate casualty of the oil glut and domestic price decontrol. Oil industry experts say, however, that many small independents, especially the crowd known in the industry as ''teapot'' refiners, may follow Energy Cooperative into extinction before the oil business recovers.

IT is the kind of apartment that you feel you could easily move right into. The rooms are bright and generous, the upholstered furniture comfortable, the bleached pine armoires nice to look at, the accessories interesting, the kitchen attractively functional and the bedroom lacy and appealing. And at a time when pastels are the dernier cri for interiors, the apartment's all-white color scheme is a relief. What is both satisfying and convenient in terms of decorating is that by limiting the palette to white and natural-colored objects, an easy decor is achieved. And, while this may not be an original decorating concept, it eminently workable.

cc22,37,14HOME C1 By GLENN COLLINS CHARLES ADDAMS - cartoonist, cemetery aficionado and Bugatti racer - eyed the approaching intersection in Hampton Bays, L.I., and kept his foot firmly on the accelerator of the Heap, his 17-foot-long van. ''Living in the Heap is like riding on a train in the great days of the first-class Pullman cars,'' he mused. ''The Heap is the poor man's Lucius Beebe railroad car.'' Suddenly the traffic light at the intersection turned amber on its way to red. Mr. Addams firmly tromped on the accelerator with his L.L. Bean hunting shoe, and the van boomed through the intersection just before the light winked red.
